Doc Brown quotes from Back to the Future (1985)

Great Scott!

Slow Down!!

The way I see it, if you're gonna build a time machine into a car, why not do it with some style?

Good evening. I'm Doctor Emmett Brown and I'm standing here in the parking lot at Twin Pines Mall. It is Saturday morning, October 26, 1985, 1:18 A.M. and this is temporal experiment number one. Please note that Einstein's clock is in precise synchronization with my control watch.

If my calculations are correct, when this baby hits eighty-eight miles per hour, you're gonna see some serious shit.

Ha! What did I tell you?! EIGHTY-EIGHT MILES PER HOUR!!! The temporal displacement occurred exactly 1:20 AM and zero seconds!

Einstein's clock is exactly one minute behind mine and still ticking!

First, you turn the time circuits on. This one tells you where you're going. This one tells you where you are. This one tells you where you were. You input your destination time on this keypad. Say you want to see the signing of the Declaration of Independence [Jul. 4, 1776] or witness the birth of Christ [Dec. 25, 0000]. Here's a red-letter date in the history of science: November 5, 1955. Yes! Of course! November 5, 1955! 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 sink, and when I came to I had a revelation! A vision! A picture in my head! A picture of this! This is what makes time travel possible: the flux capacitor! It's taken me nearly thirty years and my entire family fortune to realize 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.

Oh my god... they found me. I don't know how, but they found me. RUN FOR IT MARTY!

My God. Do you know what this means? It means that this damn thing doesn't work at all!

1.21 GIGAWATTS!!!

I'm sure that in 1985, plutonium is available in 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!

Look! There's a rhythmic ceremonial ritual coming up!

Please excuse the crudity of this model as I didn't have time to build it to scale or paint it.

Damn! Where is that kid! [looks at another watch] Damn! [and another] Damn, damn!

Don't worry. As long as you hit that wire with the connecting hook at precisely 88 miles an hour, the instant the lightning strikes the tower... everything will be fine!

It works! Ha, ha, ha, ha, ha! IT WORKS! I finally invent something that works. Somehow, we've gotta sneak this back to my laboratory. We gotta get you home!

You're not thinking fourth dimensionally!

Marty

You know, Doc, you left your equipment on all week.

My equipment? That reminds me Marty, you'd better not hook up to the amplifier. There's a slight possibility of overload.

Marty

Yeah... I'll keep that in mind.

Ha! What did I tell you?! 88 miles per hour! The temporal displacement occurred exactly 1:20 AM and zero seconds!

Marty McFly

Jesus Christ, Doc! You disintegrated Einstein!

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

Marty

Then where the hell are they?

The appropriate question is when the hell are they! You see, Einstein has just become the world's first time traveler! I sent him into the future! One minute into the future to be exact! And at precisely, 1:21 A.M. and zero seconds, we shall catch up with him and the time machine!

Marty

Wait a minute, wait a minute Doc, uh, are you telling me you built a time machine... out of a DeLorean?!

The way I see it, if you're going to build a time machine into a car, why not do it with some style? Besides, the stainless steel construction made the flux dispersal...(watch beeps) Look out! (time machine comes back)

Marty

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

Unfortunately, no. It requires something with a little more kick; Plutonium!

Marty

Uh, Plutonium... Wait a minute, are you telling me that this sucker is nuclear?!

Hey! Hey, hey, keep rolling, keep rolling there! No, no, no, no, no. This sucker's electrical, but I need a nuclear reaction to generate the 1.21 gigawatts of electricity I need.

Marty

Doc, you don't just walk into a store and buy plutonium! Did you rip that off?

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 shoddy bomb casing full of used pinball machine parts!

Marty

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

Time machine? I haven't invented any time machine.

Marty

Okay. Okay, I'll prove it to you. Look at my driver's license. Expires: 1987. Look at my birth date, for crying out loud, I haven't even been born yet! Oh, and look at this picture. It's my brother, my sister and me. Look at her sweatshirt, Doc, class of 1984.

Pretty mediocre photographic fakery; they cut off your brother's hair!

Marty

Listen, Doc, you got to believe me.

Then tell me, Future Boy. Who's President of the United States in 1985?

Marty

Ronald Reagan.

Ronald Reagan? The actor!? [chuckles in disbelief] Then who's vice-president, Jerry Lewis? I suppose Jane Wyman is the First Lady? And Jack Benny is Secretary of the Treasury!

:

What am I wearing?

Marty McFly

Oh this, this is a radiation suit.

Radiation suit? Of course! Because of all the fallout from the atomic wars! This is incredible. A portable television studio! No wonder your president has got to be an actor, he has to look good on television.

1.21 GIGAWATTS!?! 1.21 gigawatts! Great Scott!!!

Marty

Wait... what the hell is a gigawatt?!
Note: Doc Brown pronounces the term "jigga-watt".

Marty

Sounds pretty heavy.

Weight has nothing to do with it.

Marty

This is heavy, Doc.

There's that word again, 'heavy'. Why are things so heavy in the future? Is there a problem with the Earth's gravitational pull?

Marty

What?

Obviously your mother is amorously infatuated with you instead of your father.
Marty : Wait a minute, Doc. Are you trying to tell me my mom... has got the hots for me?

Precisely!

Marty

Whoa, this is heavy.

Marty

Doc!

Huh?

Marty

I have to tell you about the future!

Huh?

Marty

I have to tell you about the future!

What!

Marty

On the night I go back in time you get - [The clock chimes 10:00] ...shot.

Marty

What about all that talk about screwing up future events? The space-time continuum?

Well, I figured, what the hell!

Jennifer (after Marty discovers his new truck): How about a ride, Mister.

Marty

Jennifer! Oh man, are you a sight for sore eyes. Let me look at you.

Jennifer

Marty, your acting like you haven't seen me in a week.

Marty

I haven't.

Jennifer

Is everything okay? Is everything going all right?

Marty

Oh, yeah. Everything's great (as they are about to kiss, Doc Brown's time machine appears)

Marty! You've got to come back with me!

Marty

Where?

Back to the future.

Marty

Whoa, wait a minute, what are you doing, Doc?

I need fuel. Go ahead, quick. Get in the car!

Marty

No, no, no, no, no, no, Doc. I just got here, alright, Jennifer's here, we're gonna take the new truck for a spin.

Well, bring her along. This concerns her too.

Marty

Whoa, wait a minute, Doc. What are you talking about? What happens to us in the future? What, do we become assholes or something?

No, no, no, no, no, Marty. Both you and Jennifer turn out fine. It's your kids, Marty. Something's gotta be done about your kids!

Marty

Hey Doc, you better back up, we don't have enough road to get up to 88.

Roads? Where we're going, we don't need... roads.

Pretty mediocre photographic fakery. They cut off your brother's hair.

Marty

I'm tellin' the truth, Doc. You gotta believe me.

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

Marty

Ronald Reagan.

Ronald Reagan? The actor? [scoffs] Then who's vice-president? Jerry Lewis? I suppose Jane Wyman is the First Lady!

Marty

Whoa, wait, Doc!

And Jack Benny is Secretary of the Treasury!

Marty

Doc, you gotta listen to me!

I've had enough practical jokes for one evening! Good night, future boy! [slams door]

Marty

No, wait, Doc! The-the-the-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.

Marty

You're alive! [Doc unbuttons his suit to reveal the bulletproof vest] Bulletproof vest? How did you know? I di-I never got a chance to tell you. [Doc reveals Marty's torn-up 1955 letter which has been taped back together] What about all that talk about screwing up future events? The spacetime continuum?

Well, I figured, "what the hell?"
