A long time ago, in a galaxy far, far, away...

              A vast sea of stars serves as the backdrop for the main title. 
              War drums echo through the heavens as a rollup slowly crawls 
              into infinity.
                   It is a period of civil war. Rebel spaceships, 
                   striking from a hidden base, have won their first 
                   victory against the evil Galactic Empire.
                   During the battle, Rebel spies managed to steal 
                   secret plans to the Empire's ultimate weapon, the 
                   Death Star, an armored space station with enough 
                   power to destroy an entire planet.
                   Pursued by the Empire's sinister agents, Princess 
                   Leia races home aboard her starship, custodian of 
                   the stolen plans that can save her people and 
                   restore freedom to the galaxy...
              The awesome yellow planet of Tatooine emerges from a total 
              eclipse, her two moons glowing against the darkness. A tiny 
              silver spacecraft, a Rebel Blockade Runner firing lasers 
              from the back of the ship, races through space. It is pursed 
              by a giant Imperial Stardestroyer. Hundreds of deadly 
              laserbolts streak from the Imperial Stardestroyer, causing 
              the main solar fin of the Rebel craft to disintegrate.
              INT. REBEL BLOCKADE RUNNER - MAIN PASSAGEWAY
              An explosion rocks the ship as two robots, Artoo-Detoo (R2-
              D2) and See-Threepio (C-3PO) struggle to make their way 
              through the shaking, bouncing passageway. Both robots are 
              old and battered. Artoo is a short, claw-armed tripod. His 
              face is a mass of computer lights surrounding a radar eye. 
              Threepio, on the other hand, is a tall, slender robot of 
              human proportions. He has a gleaming bronze-like metallic 
              surface of an Art Deco design.
              Another blast shakes them as they struggle along their way.
                                    THREEPIO
                        Did you hear that? They've shut down 
                        the main reactor. We'll be destroyed 
                        for sure. This is madness!
              Rebel troopers rush past the robots and take up positions in 
              the main passageway. They aim their weapons toward the door.
                                    THREEPIO
                        We're doomed!
              The little R2 unit makes a series of electronic sounds that 
              only another robot could understand.
                                    THREEPIO
                        There'll be no escape for the Princess 
                        this time.
              Artoo continues making beeping sounds. Tension mounts as 
              loud metallic latches clank and the scream of heavy equipment 
              are heard moving around the outside hull of the ship.
                                    THREEPIO
                        What's that?
              EXT. SPACECRAFT IN SPACE
              The Imperial craft has easily overtaken the Rebel Blockade 
              Runner. The smaller Rebel ship is being drawn into the 
              underside dock of the giant Imperial starship.
              INT. REBEL BLOCKADE RUNNER
              The nervous Rebel troopers aim their weapons. Suddenly a 
              tremendous blast opens up a hole in the main passageway and 
              a score of fearsome armored spacesuited stormtroopers make 
              their way into the smoke-filled corridor.
              In a few minutes the entire passageway is ablaze with 
              laserfire. The deadly bolts ricochet in wild random patterns 
              creating huge explosions. Stormtroopers scatter and duck 
              behind storage lockers. Laserbolts hit several Rebel soldiers 
              who scream and stagger through the smoke, holding shattered 
              arms and faces.
              An explosion hits near the robots.
                                    THREEPIO
                        I should have known better than to 
                        trust the logic of a half-sized 
                        thermocapsulary dehousing assister...
              Artoo counters with an angry rebuttal as the battle rages 
              around the two hapless robots.
              EXT. TATOOINE - DESERT WASTELAND - DAY
              A death-white wasteland stretches from horizon to horizon. 
              The tremendous heat of two huge twin suns settle on a lone 
              figure, Luke Skywalker, a farm boy with heroic aspirations 
              who looks much younger than his eighteen years. His shaggy 
              hair and baggy tunic give him the air of a simple but lovable 
              lad with a prize-winning smile.
              A light wind whips at him as he adjusts several valves on a 
              large battered moisture vaporator which sticks out of the 
              desert floor much like an oil pipe with valves. He is aided 
              by a beatup tread-robot with six claw arms. The little robot 
              appears to be barely functioning and moves with jerky motions.  
              A bright sparkle in the morning sky catches Luke's eye and 
              he instinctively grabs a pair of electrobinoculars from his 
              utility belt. He stands transfixed for a few moments studying 
              the heavens, then dashed toward his dented, crudely repaired 
              Landspeeder (an auto-like transport that travels a few feet 
              above the ground on a magnetic-field). He motions for the 
              tiny robot to follow him.
                                    LUKE
                        Hurry up! Come with me! What are you 
                        waiting for?! Get in gear!
              The robot scoots around in a tight circle, stops short, and 
              smoke begins to pour out of every joint. Luke throws his 
              arms up in disgust. Exasperated, the young farm boy jumps 
              into his Landspeeder leaving the smoldering robot to hum 
              madly.
              INT. REBEL BLOCKADE RUNNER - MAIN HALLWAY
              The awesome, seven-foot-tall Dark Lord of the Sith makes his 
              way into the blinding light of the main passageway. This is 
              Darth Vader, right hand of the Emperor. His face is obscured 
              by his flowing black robes and grotesque breath mask, which 
              stands out next to the fascist white armored suits of the 
              Imperial stormtroopers. Everyone instinctively backs away 
              from the imposing warrior and a deathly quiet sweeps through 
              the Rebel troops. Several of the Rebel troops break and run 
              in a frenzied panic.
              INT. REBEL BLOCKADE RUNNER
              A woman's hand puts a card into an opening in Artoo's dome.  
              Artoo makes beeping sounds.
              INT. REBEL BLOCKADE RUNNER
              Threepio stands in a hallway, somewhat bewildered. Artoo is 
              nowhere in sight. The pitiful screams of the doomed Rebel 
              soldiers can be heard in the distance.
                                    THREEPIO
                        Artoo! Artoo-Detoo, where are you?
              A familiar clanking sound attacks Threepio's attention and 
              he spots little Artoo at the end of the hallway in a smoke-
              filled alcove. A beautiful young girl (about sixteen years 
              old) stands in front of Artoo. Surreal and out of place, 
              dreamlike and half hidden in the smoke, she finishes adjusting 
              something on Artoo's computer face, then watches as the little 
              robot joins his companion.
                                    THREEPIO
                        At last! Where have you been?
              Stormtroopers can be heard battling in the distance.
                                    THREEPIO
                        They're heading in this direction. 
                        What are we going to do? We'll be 
                        sent to the spice mine of Kessel or 
                        smashed into who knows what!
              Artoo scoots past his bronze friend and races down the 
              subhallway. Threepio chases after him.
                                    THREEPIO
                        Wait a minute, where are you going?
              Artoo responds with electronic beeps.
              INT. REBEL BLOCKADE RUNNER - CORRIDOR
              The evil Darth Vader stands amid the broken and twisted bodies 
              of his foes. He grabs a wounded Rebel Officer by the neck as 
              an Imperial Officer rushes up to the Dark Lord.
                                    IMPERIAL OFFICER
                        The Death Star plans are not in the 
                        main computer.
              Vader squeezes the neck of the Rebel Officer, who struggles 
              in vain.
                                    VADER
                        Where are those transmissions you 
                        intercepted?
              Vader lifts the Rebel off his feet by his throat.
                                    VADER
                        What have you done with those plans?
                                    REBEL OFFICER
                        We intercepted no transmissions. 
                        Aaah... This is a consular ship. 
                        Were on a diplomatic mission.
                                    VADER
                        If this is a consular ship... were 
                        is the Ambassador?
              The Rebel refuses to speak but eventually cries out as the 
              Dark Lord begins to squeeze the officer's throat, creating a 
              gruesome snapping and choking, until the soldier goes limp. 
              Vader tosses the dead soldier against the wall and turns to 
              his troops.
                                    VADER
                        Commander, tear this ship apart until 
                        you've found those plans and bring 
                        me the Ambassador. I want her alive!
              The stormtroopers scurry into the subhallways.
              INT. REBEL BLOCKADE RUNNER - SUBHALLWAY
              The lovely young girl huddles in a small alcove as the 
              stormtroopers search through the ship. She is Princess Leia 
              Organa, a member of the Alderaan Senate. The fear in her 
              eyes slowly gives way to anger as the muted crushing sounds 
              of the approaching stormtroopers grow louder. One of the 
              troopers spots her.
                                    TROOPER
                        There she is! Set for stun!
              Leia steps from her hiding place and blasts a trooper with 
              her laser pistol. She starts to run but is felled by a 
              paralyzing ray. The troopers inspect her inert body.
                                    TROOPER
                        She'll be all right. Inform Lord 
                        Vader we have a prisoner.
              INT. REBEL BLOCKADE RUNNER - SUBHALLWAY
              Artoo stops before the small hatch of an emergency lifepod. 
              He snaps the seal on the main latch and a red warning light 
              begins to flash. The stubby astro-robot works his way into 
              the cramped four-man pod.
                                    THREEPIO
                        Hey, you're not permitted in there. 
                        It's restricted. You'll be deactivated 
                        for sure..
              Artoo beeps something to him.
                                    THREEPIO
                        Don't call me a mindless philosopher, 
                        you overweight glob of grease! Now 
                        come out before somebody sees you.
              Artoo whistles something at his reluctant friend regarding 
              the mission he is about to perform.
                                    THREEPIO
                        Secret mission? What plans? What are 
                        you talking about? I'm not getting 
                        in there!
              Artoo isn't happy with Threepio's stubbornness, and he beeps 
              and twangs angrily.
              A new explosion, this time very close, sends dust and debris 
              through the narrow subhallway. Flames lick at Threepio and, 
              after a flurry of electronic swearing from Artoo, the lanky 
              robot jumps into the lifepod.
                                    THREEPIO
                        I'm going to regret this.
              INT. IMPERIAL STARDESTROYER
              On the main viewscreen, the lifepod carrying the two terrified 
              robots speeds away from the stricken Rebel spacecraft.
                                    CHIEF PILOT
                        There goes another one.
                                    CAPTAIN
                        Hold your fire. There are no life 
                        forms. It must have been short-
                        circuited.
              INT. LIFEPOD
              Artoo and Threepio look out at the receding Imperial starship.  
              Stars circle as the pod rotates through the galaxy.
                                    THREEPIO
                        That's funny, the damage doesn't 
                        look as bad from out here.
              Artoo beeps an assuring response.
                                    THREEPIO
                        Are you sure this things safe?
              EXT. TATOOINE - ANCHORHEAD SETTLEMENT - POWER STATION - DAY
              Heat waves radiate from the dozen or so bleached white 
              buildings. Luke pilots his Landspeeder through the dusty 
              empty street of the tiny settlement. An old woman runs to 
              get out of the way of the speeding vehicle, shaking her fist 
              at Luke as he flies past.
                                    WOMAN
                        I've told you kids to slow down!
              INT. POWER STATION - DAY
              Luke bursts into the power station, waking The Fixer, a rugged 
              mechanic and Camie, a sexy, disheveled girl who has been 
              asleep in his lap. They grumbled as he races through the 
              office, yelling wildly.
                                    FIXER
                        Did I hear a young noise blast through 
                        here?
                                    CAMIE
                        It was just wormie on another rampage.
              Luke bounces into a small room behind the office where Deak 
              and Windy, two tough boys about the same age as Luke, are 
              playing a computer pool-like game with Biggs, a burly, 
              handsome boy a few years older than the rest. His flashy 
              city attire is a sharp contrast to the loose-fitting tunics 
              of the farm boys. A robot repairs some equipment in the 
              background.
                                    LUKE
                        Shape it up you guys!... Biggs?
              Luke's surprise at the appearance of Biggs gives way to great 
              joy and emotion. They give each other a great bear hug.
                                    LUKE
                        I didn't know you were back! When 
                        did you get in?
                                    BIGGS
                        Just now. I wanted to surprise you, 
                        hot shot. I thought you'd be here... 
                        certainly didn't expect you to be 
                        out working.
                             (he laughs)
                                    LUKE
                        The Academy didn't change you 
                        much...but you're back so soon? Hey, 
                        what happened, didn't you get your 
                        commission?
              Biggs has an air of cool that seems slightly phony.
                                    BIGGS
                        Of course I got it. Signed aboard 
                        The Rand Ecliptic last week. First 
                        mate Biggs Darklighter at your 
                        service...
                             (he salutes)
                        ...I just came to say good-bye to 
                        all you unfortunate landlocked 
                        simpletons.
              Everyone laughs. The dazzling spectacle of his dashing friend 
              is almost too much for Luke, but suddenly he snaps out of 
              it.
                                    LUKE
                        I almost forgot. There's a battle 
                        going on! Right here in our system. 
                        Come and look!
                                    DEAK
                        Not again! Forget it.
              EXT. TATOOINE - ANCHORHEAD - SETTLEMENT - POWER STATION - 
              DAY
              The group stumbles out into the stifling desert sun. Camie 
              and The Fixer complain and are forced to shade their eyes. 
              Luke has his binoculars out scanning the heavens.
                                    LUKE
                        There they are!
              Biggs takes the binoculars from Luke as the others strain to 
              see something with the naked eye. Through the binoculars 
              Biggs sees two small silver specks.
                                    BIGGS
                        That's no battle, hot shot... they're 
                        just sitting there! Probably a 
                        freighter-tanker refueling.
                                    LUKE
                        But there was a lot of firing 
                        earlier...
              Camie grabs the binoculars away banging them against the 
              building in the process. Luke grabs them.
                                    LUKE
                        Hey, easy with those...
                                    CAMIE
                        Don't worry about it, Wormie.
              The Fixer gives Luke a hard look and the young farm boy shrugs 
              his shoulders in resignation.
                                    FIXER
                        I keep telling you, the Rebellion is 
                        a long way from here. I doubt if the 
                        Empire would even fight to keep this 
                        system. Believe me Luke, this planet 
                        is a big hunk of nothing...
              Luke agrees, although it's obvious he isn't sure why. The 
              group stumbles back into the power station, grumbling about 
              Luke's ineptitude.
              INT. REBEL BLOCKADE RUNNER - HALLWAY
              Princess Leia is led down a low-ceilinged hallway by a squad 
              of armored stormtroopers. Her hands are bound and she is 
              brutally shoved when she is unable to keep up with the briskly 
              marching troops. They stop in a smoky hallway as Darth Vader 
              emerges from the shadows. The sinister Dark Lord stares hard 
              at the frail young senator, but she doesn't move.
                                    LEIA
                        Lord Vader, I should have known. 
                        Only you could be so bold. The 
                        Imperial Senate will not sit for 
                        this, when they hear you've attacked 
                        a diplomatic...
                                    VADER
                        Don't play games with me, Your 
                        Highness. You weren't on any mercy 
                        mission this time. You passed directly 
                        through a restricted system. Several 
                        transmissions were beamed to this 
                        ship by Rebel spies. I want to know 
                        what happened to the plans they sent 
                        you.
                                    LEIA
                        I don't know what you're talking 
                        about. I'm a member of the Imperial 
                        Senate on a diplomatic mission to 
                        Alderaan...
                                    VADER
                        You're a part of the Rebel Alliance... 
                        and a traitor. Take her away!
              Leia is marched away down the hallway and into the smoldering 
              hole blasted in the side of the ship. An Imperial Commander 
              turns to Vader.
                                    COMMANDER
                        Holding her is dangerous. If word of 
                        this gets out, it could generate 
                        sympathy for the Rebellion in the 
                        senate.
                                    VADER
                        I have traced the Rebel spies to 
                        her. Now she is my only link to find 
                        their secret base!
                                    COMMANDER
                        She'll die before she tells you 
                        anything.
                                    VADER
                        Leave that to me. Send a distress 
                        signal and then inform the senate 
                        that all aboard were killed!
              Another Imperial Officer approaches Vader and the Commander. 
              They stop and snap to attention.
                                    SECOND OFFICER
                        Lord Vader, the battle station plans 
                        are not aboard this ship! And no 
                        transmissions were made. An escape 
                        pod was jettisoned during the 
                        fighting, but no life forms were 
                        aboard.
              Vader turns to the Commander.
                                    VADER
                        She must have hidden the plans in 
                        the escape pod. Send a detachment 
                        down to retrieve them. See to it 
                        personally, Commander. There'll be 
                        no one to stop us this time.
                                    COMMANDER
                        Yes, sir.
              EXT. SPACE
              The Imperial Stardestroyer comes over the surface of the 
              planet Tatooine.
              EXT. TATOOINE - DESERT
              Jundland, or "No Man's Land", where the rugged desert mesas 
              meet the foreboding dune sea. The two helpless astro-droids 
              kick up clouds of sand as they leave the lifepod and clumsily 
              work their way across the desert wasteland. The lifepod in 
              the distance rests half buried in the sand.
                                    THREEPIO
                        How did I get into this mess? I really 
                        don't know how. We seem to be made 
                        to suffer. It's our lot in life.
              Artoo answers with beeping sounds.
                                    THREEPIO
                        I've got to rest before I fall apart. 
                        My joints are almost frozen.
              Artoo continues to respond with beeping sounds.
                                    THREEPIO
                        What a desolate place this is.
              Suddenly Artoo whistles, makes a sharp right turn and starts 
              off in the direction of the rocky desert mesas. Threepio 
              stops and yells at him.
                                    THREEPIO
                        Where are you going?
              A stream of electronic noises pours forth from the small 
              robot.
                                    THREEPIO
                        Well, I'm not going that way. It's 
                        much too rocky. This way is much 
                        easier.
              Artoo counters with a long whistle.
                                    THREEPIO
                        What makes you think there are 
                        settlements over there?
              Artoo continues to make beeping sounds.
                                    THREEPIO
                        Don't get technical with me.
              Artoo continues to make beeping sounds.
                                    THREEPIO
                        What mission? What are you talking 
                        about? I've had just about enough of 
                        you! Go that way! You'll be 
                        malfunctioning within a day, you 
                        nearsighted scrap pile!
              Threepio gives the little robot a kick and starts off in the 
              direction of the vast dune sea.
                                    THREEPIO
                        And don't let me catch you following 
                        me begging for help, because you 
                        won't get it.
              Artoo's reply is a rather rude sound. He turns and trudges 
              off in the direction of the towering mesas.
                                    THREEPIO
                        No more adventures. I'm not going 
                        that way.
              Artoo beeps to himself as he makes his way toward the distant 
              mountains.
              EXT. TATOOINE - DUNE SEA
              Threepio, hot and tired, struggles up over the ridge of a 
              dune; only to find more dunes, which seem to go on for endless 
              miles.  He looks back in the direction of the now distant 
              rock mesas.
                                    THREEPIO
                        That malfunctioning little twerp. 
                        This is all his fault! He tricked me 
                        into going this way, but he'll do no 
                        better.
              In a huff of anger and frustration, Threepio knocks the sand 
              from his joints. His plight seems hopeless, when a glint of 
              reflected light in the distance reveals an object moving 
              towards him.
                                    THREEPIO
                        Wait, what's that? A transport! I'm 
                        saved!
              The bronze android waves frantically and yells at the 
              approaching transport.
                                    THREEPIO
                        Over here! Help! Please, help!
              EXT. TATOOINE - ANCHORHEAD SETTLEMENT - POWER STATION - DAY
              Luke and Biggs are walking and drinking a malt brew. Fixer 
              and the others can be heard working inside.
                                    LUKE
                             (Very animated)
                        ...so I cut off my power, shut down 
                        the afterburners and came in low on 
                        Deak's trail. I was so close I thought 
                        I was going to fry my instruments. 
                        As it was I busted up the Skyhopper 
                        pretty bad. Uncle Owen was pretty 
                        upset. He grounded me for the rest 
                        of the season. You should have been 
                        there... it was fantastic.
                                    BIGGS
                        You ought to take it easy Luke. You 
                        may be the hottest bushpilot this 
                        side of Mos Eisley, but those little 
                        Skyhoppers are dangerous. Keep it 
                        up, and one day, whammo, you're going 
                        to be nothing more than a dark spot 
                        on the down side of a canyon wall.
                                    LUKE
                        Look who's talking. Now that you've 
                        been around those giant starships 
                        you're beginning to sound like my 
                        uncle. You've gotten soft in the 
                        city...
                                    BIGGS
                        I've missed you kid.
                                    LUKE
                        Well, things haven't been the same 
                        since you left, Biggs. It's been 
                        so... quiet.
              Biggs looks around then leans close to Luke.
                                    BIGGS
                        Luke, I didn't come back just to say 
                        good-bye... I shouldn't tell you 
                        this, but you're the only one I can 
                        trust... and if I don't come back, I 
                        want somebody to know.
              Luke's eyes are wide with Biggs' seriousness and loyalty.
                                    LUKE
                        What are you talking about?
                                    BIGGS
                        I made some friends at the Academy.
                             (he whispers)
                        ...when our frigate goes to one of 
                        the central systems, we're going to 
                        jump ship and join the Alliance...
              Luke, amazed and stunned, is almost speechless.
                                    LUKE
                        Join the Rebellion?! Are you kidding! 
                        How?
                                    BIGGS
                        Quiet down will ya! You got a mouth 
                        bigger than a meteor crater!
                                    LUKE
                        I'm sorry. I'm quiet.
                             (he whispers)
                        Listen how quiet I am. You can barely 
                        hear me...
              Biggs shakes his head angrily and then continues.
                                    BIGGS
                        My friend has a friend on Bestine 
                        who might help us make contact.
                                    LUKE
                        You're crazy! You could wander around 
                        forever trying to find them.
                                    BIGGS
                        I know it's a long shot, but if I 
                        don't find them I'll do what I can 
                        on my own... It's what we always 
                        talked about. Luke, I'm not going to 
                        wait for the Empire to draft me into 
                        service. The Rebellion is spreading 
                        and I want to be on the right side -- 
                        the side I believe in.
                                    LUKE
                        And I'm stuck here...
                                    BIGGS
                        I thought you were going to the 
                        Academy next term. You'll get your 
                        chance to get off this rock.
                                    LUKE
                        Not likely! I had to cancel my 
                        application. There has been a lot of 
                        unrest among the Sandpeople since 
                        you left... they've even raided the 
                        outskirts of Anchorhead.
                                    BIGGS
                        Your uncle could hold off a whole 
                        colony of Sandpeople with one blaster.
                                    LUKE
                        I know, but he's got enough vaporators 
                        going to make the place pay off. He 
                        needs me for just one more season. I 
                        can't leave him now.
                                    BIGGS
                        I feel for you, Luke, you're going 
                        to have to learn what seems to be 
                        important or what really is important. 
                        What good is all your uncle's work 
                        if it's taken over by the Empire?... 
                        You know they're starting to 
                        nationalize commerce in the central 
                        systems... it won't be long before 
                        your uncle is merely a tenant, slaving 
                        for the greater glory of the Empire.
                                    LUKE
                        It couldn't happen here. You said it 
                        yourself. The Empire won't bother 
                        with this rock.
                                    BIGGS
                        Things always change.
                                    LUKE
                        I wish I was going... Are you going 
                        to be around long?
                                    BIGGS
                        No, I'm leaving in the morning...
                                    LUKE
                        Then I guess I won't see you.
                                    BIGGS
                        Maybe someday... I'll keep a lookout.
                                    LUKE
                        Well, I'll be at the Academy next 
                        season... after that who knows. I 
                        won't be drafted into the Imperial 
                        Starfleet that's for sure... Take 
                        care of yourself, you'll always be 
                        the best friend I've got.
                                    BIGGS
                        So long, Luke.
              Biggs turns away from his old friend and heads towards the 
              power station.
              EXT. TATOOINE - ROCK CANYON - SUNSET
              The gargantuan rock formations are shrouded in a strange 
              foreboding mist and the onimous sounds of unearthly creatures 
              fill the air. Artoo moves cautiously through the creepy rock 
              canyon, inadvertently making a loud clicking noise as he 
              goes. He hears a distant, hard, metallic sound and stops for 
              a moment. Convinced he is alone, he continues on his way.
              In the distance, a pebble tumbles down the steep canyon wall 
              and a small dark figure darts into the shadows. A little 
              further up the canyon a slight flicker of light reveals a 
              pair of eyes in the dark recesses only a few feet from the 
              narrow path.
              The unsuspecting robot waddles along the rugged trail until 
              suddenly, out of nowhere, a powerful magnetic ray shoots out 
              of the rocks and engulfs him in an eerie glow. He manages 
              one short electronic squeak before he topples over onto his 
              back. His bright computer lights flicker off, then on, then 
              off again. Out of the rocks scurry three Jawas, no taller 
              than Artoo. They holster strange and complex weapons as they 
              cautiously approach the robot. They wear grubby cloaks and 
              their faces are shrouded so only their glowing eyes can be 
              seen. They hiss and make odd guttural sounds as they heave 
              the heavy robot onto their shoulders and carry him off down 
              the trail.
              EXT. TATOOINE - ROCK CANYON - SANDCRAWLER - SUNSET
              The eight Jawas carry Artoo out of the canyon to a huge tank-
              like vehicle the size of a four-story house. They weld a 
              small disk on the side of Artoo and then put him under a 
              large tube on the side of the vehicle and the little robot 
              is sucked into the giant machine.
              The filthy little Jawas scurry like rats up small ladders 
              and enter the main cabin of the behemoth transport.
              INT. SANDCRAWLER - HOLD AREA
              It is dim inside the hold area of the Sandcrawler. Artoo 
              switches on a small floodlight on his forehead and stumbles 
              around the scrap heap. The narrow beam swings across rusty 
              metal rocket parts and an array of grotesquely twisted and 
              maimed astro-robots. He lets out a pathetic electronic whimper 
              and stumbles off toward what appears to be a door at the end 
              of the chamber.
              INT. SANDCRAWLER - PRISON AREA
              Artoo enters a wide room with a four-foot ceiling. In the 
              middle of the scrap heap sit a dozen or so robots of various 
              shapes and sizes. Some are engaged in electronic conversation, 
              while others simply mill about. A voice of recognition calls 
              out from the gloom.
                                    THREEPIO
                        Artoo-Detoo! It's you! It's you!
              A battered Threepio scrambles up to Artoo and embraces him.
              EXT. TATOOINE - ROCK CANYON - SANDCRAWLER - SUNSET
              The enormous Sandcrawler lumbers off toward the magnificent 
              twin suns, which are slowly setting over a distant mountain 
              ridge.
              EXT. TATOOINE - DESERT - DAY
              Four Imperial stormtroopers mill about in front of the half-
              buried lifepod that brought Artoo and Threepio to Tatooine. 
              A trooper yells to an officer some distance away.
                                    FIRST TROOPER
                        Someone was in the pod. The tracks 
                        go off in this direction.
              A second trooper picks a small bit of metal out of the sand 
              and gives it to the first trooper.
                                    SECOND TROOPER
                        Look, sir -- droids.
              EXT. TATOOINE - DUNES
              The Sandcrawler moves slowly down a great sand dune.
              INT. SANDCRAWLER
              Threepio and Artoo noisily bounce along inside the cramped 
              prison chamber. Artoo appears to be shut off.
                                    THREEPIO
                        Wake up! Wake up!
              Suddenly the shaking and bouncing of the Sandcrawler stops, 
              creating quite a commotion among the mechanical men.  
              Threepio's fist bangs the head of Artoo whose computer lights 
              pop on as he begins beeping. At the far end of the long 
              chamber a hatch opens, filling the chamber with blinding 
              white light. a dozen or so Jawas make their way through the 
              odd assortment of robots.
                                    THREEPIO
                        We're doomed.
              A Jawa starts moving toward them.
                                    THREEPIO
                        Do you think they'll melt us down?
              Artoo responds, making beeping sounds.
                                    THREEPIO
                        Don't shoot! Don't shoot! Will this 
                        never end?
              EXT. TATOOINE - DESERT - LARS HOMESTEAD - AFTERNOON
              The Jawas mutter gibberish as they busily line up their 
              battered captives, including Artoo and Threepio, in front of 
              the enormous Sandcrawler, which is parked beside a small 
              homestead consisting of three large holes in the ground 
              surrounded by several tall moisture vaporators and one small 
              adobe block house.
              The Jawas scurry around fussing over the robots, straightening 
              them up or brushing some dust from a dented metallic elbow. 
              The shrouded little creatures smell horribly, attracting 
              small insects to the dark areas when their mouths and nostrils 
              should be.
              Out of the shadows of a dingy side-building limps Owen Lars, 
              a large burly man in his mid-fifties. His reddish eyes are 
              sunken in a dust-covered face. As the farmer carefully 
              inspects each robot, he is closely followed by his slump- 
              shouldered nephew, Luke Skywalker. One of the vile little 
              Jawas walks ahead of the farmer spouting an animated sales 
              pitch in a queer, unintelligible language.
              A voice calls out from one of the huge holes that form the 
              homestead. Luke goes over to the edge and sees his Aunt Beru 
              standing in the main courtyard.
                                    BERU
                        Luke, tell Owen that if he gets a 
                        translator to be sure it speaks Bocce.
                                    LUKE
                        It looks like we don't have much of 
                        a choice but I'll remind him.
              Luke returns to his uncle as they look over the equipment 
              for sale with the Jawa leader.
                                    OWEN
                        I have no need for a protocol droid.
                                    THREEPIO
                             (quickly)
                        Sir -- not in an environment such as 
                        this -- that's why I've also been 
                        programmed for over thirty secondary 
                        functions that...
                                    OWEN
                        What I really need is a droid that 
                        understands the binary language of 
                        moisture vaporators.
                                    THREEPIO
                        Vaporators! Sir -- My first job was 
                        programming binary load lifter... 
                        very similar to your vaporators. You 
                        could say...
                                    OWEN
                        Do you speak Bocce?
                                    THREEPIO
                        Of course I can, sir. It's like a 
                        second language for me... I'm as 
                        fluent in Bocce...
                                    OWEN
                        All right shut up!
                             (turning to Jawa)
                        I'll take this one.
                                    THREEPIO
                        Shutting up, sir.
                                    OWEN
                        Luke, take these two over to the 
                        garage, will you? I want you to have 
                        both of them cleaned up before dinner.
                                    LUKE
                        But I was going into Toshi Station 
                        to pick up some power converters...
                                    OWEN
                        You can waste time with your friends 
                        when your chores are done. Now come 
                        on, get to it!
                                    LUKE
                        All right, come on! And the red one, 
                        come on. Well, come on, Red, let's 
                        go.
              As the Jawas start to lead the three remaining robots back 
              into the Sandcrawler, Artoo lets out a pathetic little beep 
              and starts after his old friend Threepio. He is restrained 
              by a slimy Jawa, who zaps him with a control box.
              Owen is negotiating with the head Jawa. Luke and the two 
              robots start off for the garage when a plate pops off the 
              head of the red astro-droid's head plate and it sparks wildly.
                                    LUKE
                        Uncle Owen...
                                    OWEN
                        Yeah?
                                    LUKE
                        This R2 unit has a bad motivator. 
                        Look!
                                    OWEN
                             (to the head Jawa)
                        Hey, what're you trying to push on 
                        us?
              The Jawa goes into a loud spiel. Meanwhile, Artoo has sneaked 
              out of line and is moving up and down trying to attract 
              attention. He lets out with a low whistle. Threepio taps 
              Luke on the shoulder.
                                    THREEPIO
                             (pointing to Artoo)
                        Excuse me, sir, but that R2 unit is 
                        in prime condition. A real bargain.
                                    LUKE
                        Uncle Owen...
                                    OWEN
                        Yeah?
                                    LUKE
                        What about that one?
                                    OWEN
                             (to Jawa)
                        What about that blue one? We'll take 
                        that one.
              With a little reluctance the scruffy dwarf trades the damaged 
              astro-droid for Artoo.
                                    LUKE
                        Yeah, take it away.
                                    THREEPIO
                        Uh, I'm quite sure you'll be very 
                        pleased with that one, sir. He really 
                        is in first-class condition. I've 
                        worked with him before. Here he comes.
              Owen pays off the whining Jawa as Luke and the two robots 
              trudge off toward a grimy homestead entry.
                                    LUKE
                        Okay, let's go.
                                    THREEPIO
                             (to Artoo)
                        Now, don't you forget this! Why I 
                        should stick my neck out for you is 
                        quite beyond my capacity!
              INT. LARS HOMESTEAD - GARAGE AREA - LATE AFTERNOON
              The garage is cluttered and worn, but a friendly peaceful 
              atmosphere permeates the low grey chamber. Threepio lowers 
              himself into a large tub filled with warm oil. Near the 
              battered Landspeeder little Artoo rests on a large battery 
              with a cord to his face.
                                    THREEPIO
                        Thank the maker! This oil bath is 
                        going to feel so good. I've got such 
                        a bad case of dust contamination, I 
                        can barely move!
              Artoo beeps a muffled reply. Luke seems to be lost in thought 
              as he runs his hand over the damaged fin of a small two-man 
              Skyhopper spaceship resting in a low hangar off the garage. 
              Finally Luke's frustrations get the better of him and he 
              slams a wrench across the workbench.
                                    LUKE
                        It just isn't fair. Oh, Biggs is 
                        right. I'm never gonna get out of 
                        here!
                                    THREEPIO
                        Is there anything I might do to help?
              Luke glances at the battered robot. A bit of his anger drains 
              and a tiny smile creeps across his face.
                                    LUKE
                        Well, not unless you can alter time, 
                        speed up the harvest, or teleport me 
                        off this rock!
                                    THREEPIO
                        I don't think so, sir. I'm only a 
                        droid and not very knowledgeable 
                        about such things. Not on this planet, 
                        anyways. As a matter of fact, I'm 
                        not even sure which planet I'm on.
                                    LUKE
                        Well, if there's a bright center to 
                        the universe, you're on the planet 
                        that it's farthest from.
                                    THREEPIO
                        I see, sir.
                                    LUKE
                        Uh, you can call me Luke.
                                    THREEPIO
                        I see, sir Luke.
                                    LUKE
                             (laughing)
                        Just Luke.
                                    THREEPIO
                        And I am See-Threepio, human-cyborg 
                        relations, and this is my counterpart, 
                        Artoo-Detoo.
                                    LUKE
                        Hello.
              Artoo beeps in response. Luke unplugs Artoo and begins to 
              scrape several connectors on the robot's head with a chrome 
              pick. Threepio climbs out of the oil tub and begins wiping 
              oil from his bronze body.
                                    LUKE
                        You got a lot of carbon scoring here. 
                        It looks like you boys have seen a 
                        lot of action.
                                    THREEPIO
                        With all we've been through, sometimes 
                        I'm amazed we're in as good condition 
                        as we are, what with the Rebellion 
                        and all.
                                    LUKE
                        You know of the Rebellion against 
                        the Empire?
                                    THREEPIO
                        That's how we came to be in your 
                        service, if you take my meaning, 
                        sir.
                                    LUKE
                        Have you been in many battles?
                                    THREEPIO
                        Several, I think. Actually, there's 
                        not much to tell. I'm not much more 
                        than an interpreter, and not very 
                        good at telling stories. Well, not 
                        at making them interesting, anyways.
              Luke struggles to remove a small metal fragment from Artoo's 
              neck joint. He uses a larger pick.
                                    LUKE
                        Well, my little friend, you've got 
                        something jammed in here real good. 
                        Were you on a cruiser or...
              The fragment breaks loose with a snap, sending Luke tumbling 
              head over heels. He sits up and sees a twelve-inch three-
              dimensional hologram of Leia Organa, the Rebel senator, being 
              projected from the face of little Artoo. The image is a 
              rainbow of colors as it flickers and jiggles in the dimly 
              lit garage. Luke's mouth hangs open in awe.
                                    LEIA
                        Help me, Obi-Wan Kenobi. You're my 
                        only hope.
                                    LUKE
                        What's this?
              Artoo looks around and sheepishly beeps an answer for Threepio 
              to translate. Leia continues to repeat the sentence fragment 
              over and over.
                                    THREEPIO
                        What is what?!? He asked you a 
                        question...
                             (pointing to Leia)
                        What is that?
              Artoo whistles his surprise as he pretends to just notice 
              the hologram. He looks around and sheepishly beeps an answer 
              for Threepio to translate. Leia continues to repeat the 
              sentence fragment over and over.
                                    LEIA
                        Help me, Obi-Wan Kenobi. You're my 
                        only hope. Help me, Obi-Wan Kenobi. 
                        You're my only hope.
                                    THREEPIO
                        Oh, he says it's nothing, sir. Merely 
                        a malfunction. Old data. Pay it no 
                        mind.
              Luke becomes intrigued by the beautiful girl.
                                    LUKE
                        Who is she? She's beautiful.
                                    THREEPIO
                        I'm afraid I'm not quite sure, sir.
                                    LEIA
                        Help me, Obi-Wan Kenobi...
                                    THREEPIO
                        I think she was a passenger on our 
                        last voyage. A person of some 
                        importance, sir -- I believe. Our 
                        captain was attached to...
                                    LUKE
                        Is there more to this recording?
              Luke reaches out for Artoo but he lets out several frantic 
              squeaks and a whistle.
                                    THREEPIO
                        Behave yourself, Artoo. You're going 
                        to get us in trouble. It's all right, 
                        you can trust him. He's our new 
                        master.
              Artoo whistles and beeps a long message to Threepio.
                                    THREEPIO
                        He says he's the property of Obi-Wan 
                        Kenobi, a resident of these parts. 
                        And it's a private message for him. 
                        Quite frankly, sir I don't know what 
                        he's talking about. Our last master 
                        was Captain Antilles, but with what 
                        we've been through, this little R2 
                        unit has become a bit eccentric.
                                    LUKE
                        Obi-Wan Kenobi? I wonder if he means 
                        old Ben Kenobi?
                                    THREEPIO
                        I beg your pardon, sir, but do you 
                        know what he's talking about?
                                    LUKE
                        Well, I don't know anyone named Obi-
                        Wan, but old Ben lives out beyond 
                        the dune sea. He's kind of a strange 
                        old hermit.
              Luke's gazes at the beautiful young princess for a few 
              moments.
                                    LUKE
                        I wonder who she is. It sounds like 
                        she's in trouble. I'd better play 
                        back the whole thing.
              Artoo beeps something to Threepio.
                                    THREEPIO
                        He says the restraining bolt has 
                        short circuited his recording system. 
                        He suggests that if you remove the 
                        bolt, he might be able to play back 
                        the entire recording.
              Luke looks longingly at the lovely, little princess and hasn't 
              really heard what Threepio has been saying.
                                    LUKE
                        H'm? Oh, yeah, well, I guess you're 
                        too small to run away on me if I 
                        take this off! Okay.
              Luke takes a wedged bar and pops the restraining bolt off 
              Artoo's side.
                                    LUKE
                        There you go.
              The princess immediately disappears...
                                    LUKE
                        Well, wait a minute. Where'd she go? 
                        Bring her back! Play back the entire 
                        message.
              Artoo beeps an innocent reply as Threepio sits up in 
              embarrassment.
                                    THREEPIO
                        What message? The one you're carrying 
                        inside your rusty innards!
              A women's voice calls out from another room.
                                    AUNT BERU
                        Luke? Luke! Come to dinner!
              Luke stands up and shakes his head at the malfunctioning 
              robot.
                                    LUKE
                        All right, I'll be right there, Aunt 
                        Beru.
                                    THREEPIO
                        I'm sorry, sir, but he appears to 
                        have picked up a slight flutter.
              Luke tosses Artoo's restraining bolt on the workbench and 
              hurries out of the room.
                                    LUKE
                        Well, see what you can do with him. 
                        I'll be right back.
