Bob Gale - BACK TO THE FUTURE

Lorraine: And he could sleep in my room.

Marty: I gotta go, uh, I gotta go. Thanks very much, it was wonderful, you were all great. See you all later, (to himself) much later.

Marty leaves. Stella turns to her husband.

Stella: He's a very strange young man.

Sam: He's an idiot, comes from upbringing, parents were probably idiots too. Lorraine, if you ever have a kid like that, I'll disown you.

Lorraine looks at where Marty was, and smiles to herself.

Cut to 1640 Riverside Drive. It's a huge mansion! At the end of the driveway is the garage, where Doc lives in 1985. Marty knocks on the door. DOC opens it. He's got something on his head - one of his inventions. There's also a plaster on his forehead as a result of the bruise he had after falling off his toilet.

Marty: Doc?

Doc: Don't say a word.

Doc ushers Marty inside and connects the invention to him.

Marty: Doc.

Doc: I don't wanna know your name. I don't wanna know anything about you.

Marty: Listen, Doc.

Doc: Quiet.

Marty: Doc, Doc, it's me, Marty.

Doc: Don't tell me anything.

Marty: Doc, you gotta help...

Doc: Quiet, quiet. I'm gonna read your thoughts. Let's see now, you've come from a great distance?

Marty: Yeah, exactly.

Doc: Don't tell me! Uh, you want me to buy a subscription to the Saturday Evening Post?

Marty: No.

Doc: Not a word, not a word, not a word now. Quiet, uh, donations, you want me to make a donation to the coast guard youth auxiliary?

Marty: Doc, I'm from the future. I came here in a time machine that you invented. Now, I need your help to get back to the year 1985.

Doc is astounded!

Doc: My God, do you know what this means? It means that this damn thing doesn't work at all!

Doc takes his mind reading invention off and puts it away.

Marty: Doc, you gotta help me. You're the only one who knows how your time machine works.

Doc: (muttering) Time machine, I haven't invented any time machine.

Marty: OK, All right, I'll prove it to you.

Marty gets out his wallet and shows it to Doc.

Marty: Look at my driver's license, expires 1987. Look at my birthday, for crying out loud. I haven't even been born yet! And, look at this picture, my brother, my sister, and me.

Marty shows Doc a picture of him, Dave and Linda. Linda is wearing a class of '84 sweatshirt. The top of Dave's head is also missing.

Marty: Look at the sweatshirt, Doc, class of 1984!

Doc: Pretty mediocre photographic fakery, they cut off your brother's hair.

Marty: I'm telling the truth, Doc, you gotta believe me.

Doc: So tell me, Future Boy, who's President of the United States in 1985?

Marty: Ronald Reagan.

Doc: Ronald Reagan, the actor? Then who's Vice President? Jerry Lewis?

During the following Doc leaves his house and goes to his garage with some things. Marty follows him.

Doc: I suppose Jane Wyman is the First Lady.

Marty: Whoa, wait, Doc.

Doc: And Jack Benny is Secretary of the Treasury.

Marty: Look, you gotta listen to me.

Doc: I've had enough practical jokes for one evening. Good night, Future Boy!!

Doc closes the garage door. Marty talks desperately through it to him.

Marty: No wait, Doc, the bruise, the bruise on your head, I know how that happened, you told me the whole story. You were standing on your toilet and you were hanging a clock, and you fell, and you hit your head on the sink, and that's when you came up with the idea for the flux capacitor, which is what makes time travel possible.

Doc opens the door and stares at Marty with amazement. He was telling the truth! Cut to outside the Lyon Estate signs. Doc and Marty are looking at the DeLorean.

Marty: Something wrong with the starter, so I hid it.

Doc: After I fell off my toilet, I drew this.

Doc shows Marty a drawing of the flux capacitor.

Marty: Flux capacitor.

Marty shows Doc the real thing. Doc is amazed.

Doc: It works, ha, ha, ha, ha, it works! I finally invent something that works!

Marty: Bet your ass it works.

Doc: Well, now we gotta sneak this back into my laboratory. We've gotta get you home!

Back at the lab, Marty is plugging the video camera into Doc's TV.

Marty: OK Doc, this is it.

The video starts playing. 1985 DOC starts speaking on the video.

1985 Doc: (on video) Never mind that, never mind that now...

Doc: Why that's me! Look at me, I'm an old man!

1985 Doc: (on video) Good evening, I'm Dr Emmett Brown, I'm standing here on the parking lot of Twin Pines Mall. It's Saturday morning, October 26th 1985.....

Doc: Thank God I still got my hair. What on Earth is that thing I'm wearing?

Marty: Well, that's a radiation suit.

He starts fast-forwarding the video.

Doc: Radiation suit, of course, 'cause of all of the fall out from the atomic wars. This is truly amazing, a portable television studio. No wonder your President has to be an actor, he's gotta look good on television.

Marty: Whoa, this is it, this is the part coming up, Doc.

1985 Doc: (on video) No, no, no, this sucker's electrical, but I need a nuclear reaction to generate the 1.21 gigawatts of electricity...

Doc: What did I just say?

Marty rewinds the tape.

1985 Doc: (on video) No, no, no, this sucker's electrical, but I need a nuclear reaction to generate the 1.21 gigawatts of electricity that I need.

Doc: 1.21 gigawatts? 1.21 gigawatts! Great Scott!

Marty: What the hell is a gigawatt?

Doc runs over to his portraits.

Doc: How could I have been so careless? 1.21 gigawatts! Tom (re: Thomas Edison) , how am I gonna generate that kind of power? It can't be done, it can't!

Marty: Doc, look, all we need is a little plutonium!

Doc: (sarcastically) I'm sure that in 1985, plutonium is available at every corner drug store, but in 1955, it's a little hard to come by. Marty, I'm sorry, but I'm afraid you're stuck here.

Marty: Whoa, whoa Doc, stuck here, I can't be stuck here, I got a life in 1985! I got a girl!

Doc: Is she pretty?

Marty: Doc, she's beautiful. She's crazy about me.

Marty gets the flyer out of his pocket.

Marty: Look at this, look what she wrote me, Doc. That says it all. Doc, you're my only hope.

Doc: Marty, I'm sorry, but the only power source capable of generating 1.21 gigawatts of electricity is a bolt of lightning.

Marty realises something!

Marty: What did you say?

Doc: A bolt of lightning, unfortunately, you never know when or where it's ever gonna strike.

Marty shows Doc the flyer.

Marty: We do now.

Cut to Doc examining the flyer. He's walking around, thinking as he talks.

Doc: This is it. This is the answer. It says here that a bolt of lightning is gonna strike the clocktower precisely at 10.04pm next Saturday night. If we could somehow harness this bolt of lightning, channel it into the flux capacitor, it just might work. Next Saturday night, we're sending you back to the future.

Marty: OK, All right, Saturday is good, Saturday's good, I could spend a week in 1955. I could hang out, you could show me around.

Doc: Marty, that's completely out of the question, you must not leave this house. You must not see anybody or talk to anybody. Anything you do could have serious replications on future events. Do you understand?

Marty: Yeah, sure, OK.

Doc: Marty, have you interacted with anybody else today, besides me?

Marty: (mumbling a bit) Um, yeah, well I might have sort of ran into my parents.
