Bob Gale - BACK TO THE FUTURE

Music: Time Bomb Town by Lindsay Buckingham (playing on Marty's radio)

Marty's room. He's asleep. Suddenly the 'phone rings, waking Marty up. He answers it.

Marty: Hello.

Doc: (v.o) Marty, you didn't fall asleep, did you?

Marty looks at his watch.

Marty: Uh Doc, uh no. No, don't be silly.

Doc: (v.o) Listen, this is very important, I forgot my video camera, could you stop by my place and pick it up on your way to the mall?

Marty: Um, yeah, I'm on my way.

Cut to outside Twin Pines Mall. Marty skateboards down into the Mall. Inside the parking lot is a big white van, Dr E Brown Enterprises. A dog, EINSTEIN, is sitting by it. Marty goes towards him.

Marty: Einstein, hey Einstein, where's the Doc, boy, huh?

The doors of the van open, and smoke comes out. It's followed by a DeLorean sports car, reversing back out of the van and into the parking lot. The license plate reads OUTATIME. DR EMMETT L DOC BROWN then gets out of the car. He's an elderly man, aged 65, and has long, white hair. He's wearing a radiation suit and looks very much your typical wild scientist.

Marty: Doc?

Doc: Marty, you made it!

Marty: Yeah!

Doc: Welcome to my latest experiment. It's the one I've been waiting for all my life.

Marty: Um, well it's a DeLorean, right?

Doc: Bare with me, Marty, all of your questions will be answered. Roll tape...

Marty: OK.

Doc: ...and we'll proceed.

Marty: Doc, is that a de...

Doc: Never mind that now, never mind that now.

Marty: All right, I'm ready.

Marty starts filming Doc .

Doc: Good evening, I'm Dr Emmett Brown. I'm standing on the parking lot of Twin Pines Mall. It's Saturday morning, October 26th 1985, 1.18am and this is temporal experiment number one. C'mon, Einie.

During the following Einstein gets into the DeLorean. He has a clock attached to his collar.

Doc: Hey, hey boy, get in there, that a boy, in you go, sit down, put your seatbelt on, that's it!

Marty: Whoa, whoa, whoa, OK.

Doc: Please note that Einstein's clock is in complete synchronisation with my control watch. Got it?

Both clocks - the one in Doc's hands and the one around Einstein's neck - say 1.19.

Marty: Right, check, Doc.

Doc: Good. Have a good trip Einstein, watch your head.

Doc shuts the car door and gets out a remote control for the car. Amongst other things it has a digital speedometer on it.

Marty: You have this thing hooked up to the car?

Doc: Watch this.

Marty: Yeah, OK, got it.

He starts filming. The car starts driving itself - it is being controlled from the remote!

Marty: Jesus!

Marty turns to Doc, inadvertently filming him.

Doc: Not me, the car, the car!

Marty films the car.

Doc: If my calculations are correct, when this baby hits 88 miles per hour, your gonna see some serious shit. Watch this, watch this.

Doc lets go of the lever. The car heads towards him and Marty. Then as it hits 88 miles per hour, it lets off a blue glow and disappears, leaving behind two fire trails which almost hit the feet of Marty and Doc. The licence plate falls off the car and spins around on the ground.

Doc: Ha, what did I tell you, 88 miles per hour! The temporal displacement occurred at exactly 1.20am and zero seconds!

Marty picks up the OUTATIME plate.

Marty: Hot, Jesus Christ, Doc. Jesus Christ, Doc, you disintegrated Einstein!

Doc: Calm down, Marty, I didn't disintegrate anything. The molecular structure of Einstein and the car are completely intact.

Marty: Where the hell are they?

Doc: The appropriate question is, when the hell are they! Einstein has just become the world's first time traveller! I sent him into the future. 1 minute into the future to be exact. And at exactly 1.21am we should catch up with him and the time machine.

Marty: Wait a minute, wait a minute, Doc, are you telling me that you built a time machine... out of a DeLorean?

Doc: The way I see it, if you're gonna build a time machine into a car why not do it with some style. Besides, the stainless, steel construction made the flux dispersal.....

Doc checks his watch.

Doc: Look out!

The DeLorean reappears. It's steaming. Doc walks over to it and touches it.

Marty: What, what is it hot?

Doc: It's cold, damn cold. (Opens the door) Ha, ha, ha, Einstein, you little devil. Einstein's clock is exactly one minute behind mine, it's still ticking.

Doc's clock says 1.22, Einstein's clock says 1.21. Doc unbuckles Einstein's seatbelt and he runs happily into the van.

Marty: He's all right.

Doc: He's fine, and he's completely unaware that anything happened. As far as he's concerned the trip was instantaneous. That's why Einstein's watch is exactly one minute behind mine. He skipped over that minute to instantly arrive at this moment in time. Come here, I'll show you how it works. First, you turn the time circuits on.

Doc does so. Inside are three panels, each with a different LED display.

Doc: This readout tells you where you're going, this one tells you where you are, this one tells you where you were. You input the destination time on this keypad. Say, you wanna see the signing of the Declaration of Independence...

Doc types in July 4th 1776.

Doc: ...or witness the birth or Christ.

Doc types in December 25th 0000.

Doc: Here's a red-letter date in the history of science, November 5th (surprised) 1955.

Doc types in November 5th 1955 and then realises.

Doc: Yes, of course, November 5th 1955!

Marty: What, I don't get what happened.

Doc: That was the day I invented time travel. I remember it vividly. I was standing on the edge of my toilet hanging a clock, the porcelain was wet, I slipped, hit my head on the edge of the sink. And when I came to, I had a revelation, a picture, a picture in my head, a picture of this.

Doc shows Marty the this.

Doc: This is what makes time travel possible. The flux capacitor.

Marty: The flux capacitor.

Doc: It's taken me almost 30 years and my entire family fortune to realise the vision of that day. My God, has it been that long? Things have certainly changed around here. I remember when this was all farmland as far as the eye could see. Old Man Peabody, owned all of this. He had this crazy idea about breeding pine trees.

Marty: This is uh, this is heavy duty, Doc, this is great. Uh, does it run on regular unleaded gasoline?

Doc: Unfortunately no, it requires something with a little more kick - plutonium!

Marty: Uh, plutonium, wait a minute, are you telling me that this sucker's nuclear?

Doc notices Marty has let the camera drop.

Doc: Hey, hey, keep rolling, keep rolling there. No, no, no, no, this sucker's electrical. But I need a nuclear reaction to generate the 1.21 gigawatts of electricity that I need.

Marty: Doc, you don't just walk into a store and ask for plutonium! Did you rip this off?

Doc comes to Marty waving off the idea, and then:

Doc: Of course, from a group of Libyan Nationalists. They wanted me to build them a bomb, so I took their plutonium and in turn gave them a shiny bomb case full of used pinball machine parts!

Marty: Jesus.

Doc: Let's get you into a radiation suit, we must prepare to reload.

A few minutes later, Doc has put more plutonium into the DeLorean and Marty is in a radiation suit.

Doc: Safe now, everything's let lined. Don't you lose those tapes now, we'll need a record. Yep, yep. I almost forgot my luggage. Who knows if they've got cotton underwear in the future. I'm allergic to all synthetics.
