Dr. Emmett Brown Quotes in Back to the Future (1985)

Dr. Emmett Brown: If my calculations are correct, when this baby hits 88 miles per hour... you're gonna see some serious shit.

[repeated Line]

Dr. Emmett Brown: Great Scott!

[last lines]

Marty McFly: Hey, Doc, we better back up. We don't have enough road to get up to 88.

Dr. Emmett Brown: Roads? Where we're going, we don't need roads.

Marty McFly: Whoa. Wait a minute, Doc. Are you trying to tell me that my mother has got the hots for me?

Dr. Emmett Brown: Precisely.

Marty McFly: Whoa. This is heavy.

Dr. Emmett Brown: 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 McFly: Wait a minute. Wait a minute, Doc. Ah... Are you telling me that you built a time machine... out of a DeLorean?

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

Dr. Emmett Brown: [Marty is showing Doc Brown the flux capacitor in the DeLorean time vehicle] It works! It works!

[grabs Marty]

Dr. Emmett Brown: I finally invent something that works!

Marty McFly: [quietly] You bet your ass it works.

[Marty and Doc observe George's incompetence in 1955]

Dr. Emmett Brown: Which one's your pop?

Marty McFly: [points him out] That's him.

[they see him getting kicked around by other school bullies]

George McFly: [has a "kick me" sign on his back] Okay. Okay, you guys. Ah-ha-ha-ha. Very funny. You guys are being real mature.

Dr. Emmett Brown: Maybe you were adopted.

[Dr. Emmett Brown is doubting Marty McFly's story about that he is from the future]

Dr. Emmett Brown: Then tell me, future boy, who's President of the United States in 1985?

Marty McFly: Ronald Reagan.

Dr. Emmett Brown: Ronald Reagan? The actor?

[chuckles in disbelief]

Dr. Emmett Brown: Then who's vice president? Jerry Lewis?

[rushing out and down a hill toward his laboratory]

Dr. Emmett Brown: I suppose Jane Wyman is the First Lady!

Marty McFly: [following Doc] Whoa. Wait, Doc!

Dr. Emmett Brown: And Jack Benny is secretary of the treasury.

Marty McFly: [outside the lab door] Doc, you gotta listen to me.

Dr. Emmett Brown: [opens the door to the lab] I've had enough practical jokes for one evening. Good night, future boy!

[closes the door leaving Marty outside]

Marty McFly: No, wait, Doc. Doc. The-the-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,

[somberly]

Marty McFly: which is what makes time travel possible.

[Doc opens the door and looks at Marty with a stunned look on his face]

1955 radio weatherman: [It's Marty's last night in 1955. Doc is setting up the cable that will channel the lightning bolt into the time machine] ... Hill Valley area weather this Saturday night. Mostly clear, with some scattered clouds. Lows tonight in the upper 40s.

Dr. Emmett Brown: Are you sure about this storm?

Marty McFly: Since when can weathermen predict the weather, let alone the future?

Dr. Emmett Brown: You know, Marty, I'm gonna be very sad to see you go. You've really made a difference in my life. You've given me something to shoot for. Just knowing that I'm going to be around to see 1985. That I'm gonna succeed in this!

[gestures at time machine]

Dr. Emmett Brown: That I'm gonna have a chance to travel through time!

[Marty looks solemn, knowing that Doc is destined to be murdered before he gets to use the time machine himself]

Dr. Emmett Brown: It's gonna be really hard waiting 30 years before I can talk to you about everything that's happened in the past few days. I'm really gonna miss you, Marty.

Marty McFly: I'm really gonna miss *you*.

[pause]

Marty McFly: Doc, about the future...

Dr. Emmett Brown: No! Marty! We've already agreed that having information about the future can be extremely dangerous. Even if your intentions are good, it can backfire drastically!

[Marty nods reluctantly]

Dr. Emmett Brown: Whatever you've got to tell me, I'll find out through the natural course of time.

[pacing in front of the clock tower]

Dr. Emmett Brown: [looks at his watch] Damn! Where is that kid?

[looks at a small alarm clock in his other hand]

Dr. Emmett Brown: Damn!

[looks at a second watch on his other wrist]

Dr. Emmett Brown: Damn! Damn!

Marty McFly: This is heavy.

Dr. Emmett Brown: Weight has nothing to do with it.

Dr. Emmett Brown: [Deleted Scene, Doc Brown uses a sound fork and hits the time machine with the sound fork and frantically steps back] I knew, I knew it, I knew it.

Marty McFly: Doc, do you have a 75-ohm matching transformer?

Dr. Emmett Brown: What?

Marty McFly: [Realizing where in time he is] Not invented yet. That's right.

Dr. Emmett Brown: [Walks over to his future self's suit case] So, these are my personal belongings, huh?

Marty McFly: Yeah.

Dr. Emmett Brown: [Opens up the suit case and picks up a hair dryer] What's this thing?

Marty McFly: It's a hair dryer.

Dr. Emmett Brown: A hair dryer? Don't they have towels in the future?

Dr. Emmett Brown: [Picks up a pair of underwear] Oh, look at these underpants. They're all made of cotton. I though for sure we'd all be wearing disposable paper garments by 1985.

Dr. Emmett Brown: [Picks up a Playboy Magazine] What's... this?

[Looks at the magazine]

Dr. Emmett Brown: [exclaims] Suddenly, the future's looking a *whole* lot better.

Dr. Emmett Brown: [holding Marty's video camera] No wonder your president has to be an actor. He's gotta look good on television.

Dr. Emmett Brown: Let me show you my plan for sending you home. Please excuse the crudity of this model. I didn't have time to build it to scale or paint it.

[reveals intricate tabletop model of the town square]

Marty McFly: [impressed] It's good.

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

Marty McFly: [startled] What did you say?

Dr. Emmett Brown: A bolt of lighting. Unfortunately, you never know when or where it's ever gonna strike.

Marty McFly: We do now.

[hands Doc the "Save the Clock Tower" flyer]

[referring to the DeLorean]

Marty McFly: [looks through a camcorder] This is heavy-duty, Doc. This is great. Uh, does it run, like, on regular unleaded gasoline?

Dr. Emmett Brown: Unfortunately, no. It requires something with a little more kick. Plutonium.

Marty McFly: Um, plutonium. Wait a minute. Are...

[lowers the camcorder]

Marty McFly: Are you telling me that this sucker is NUCLEAR?

Dr. Emmett Brown: Hey, hey, hey! Keep rolling. Keep rolling there.

[Marty raises the camcorder]

Dr. Emmett Brown: 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 McFly: Doc, you don't just walk into a store and-and buy plutonium! Did you rip that off?

Dr. Emmett Brown: 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. Come on! Let's get you a radiation suit. We must prepare to reload.

[Marty sees the outside of the Hill Valley High School in 1955]

Marty McFly: Whoa. They really cleaned this place up. Looks brand-new.

[Marty and Doc walk toward the building]

Dr. Emmett Brown: Now, remember. According to my theory, you interfered with your parents' first meeting. If they don't meet, they won't fall in love, they won't get married and they won't have kids. That's why your older brother's disappearing from that photograph. Your sister will follow, and unless you repair the damage, you'll be next.

Marty McFly: Sounds pretty heavy.

Dr. Emmett Brown: Weight has nothing to do with it.

Dr. Emmett Brown: [reads the "Save the Clock Tower" flyer and reacts with hope] This is it! This is the answer. It says here that a bolt of lightning is going to strike the clock tower at precisely 10:04 p.m. next Saturday night! If... If we could somehow harness this lightning... channel it into the flux capacitor... it just might work. Next Saturday night, we're sending you back to the future!

[1955 Doc is watching a video of 1985 Doc]

Dr. Emmett Brown: What on Earth is this thing I'm wearing?

Marty McFly: Ah, this, this is a radiation suit.

Dr. Emmett Brown: Radiation suit? Of course. 'Cause of all the fallout from the atomic wars.

[on the phone while all the clocks chime at once]

Dr. Emmett Brown: Are those my clocks I hear?

Marty McFly: Yeah, it's 8:00.

Dr. Emmett Brown: Perfect! My experiment worked! They're all exactly 25 minutes slow!

Marty McFly: Wait a minute - wait a minute, Doc... are you telling me that it's 8:25?

Dr. Emmett Brown: Precisely.

Marty McFly: Damn! I'm late for school!

[hangs up, grabs his skateboard and rushes out]

Marty McFly: [Doc has just been shot. Marty runs over to him] Doc! Doc!

Marty McFly: [Marty turns Doc's body over to reveal it is apparently bullet-ridden and lifeless. Marty begins to cry] No! No!

Marty McFly: [Doc suddenly blinks and sits up] You're alive.

Marty McFly: [Doc unzips his radiation suit to reveal a bulletproof vest underneath] Bulletproof vest? How did you know? I never got a chance to tell you.

Marty McFly: [Doc smiles and removes a weathered piece of paper from his pocket. Marty unfolds the paper to reveal it is the warning letter he had written in 1955, taped back together] What about all that talk about screwing up future events? The space-time continuum?

Dr. Emmett Brown: Well, I figured, what the hell?

[seeing a poster for the Enchantment Under the Sea dance]

Dr. Emmett Brown: Look! There's a rhythmic ceremonial ritual coming up.

Marty McFly: Of course! The Enchantment Under the Sea dance! They're supposed to go to this. That's where they kiss for the first time.

Dr. Emmett Brown: All right, kid. You stick to your father like glue and make sure he takes her to that dance.

Dr. Emmett Brown: [Doc has just finished the final preparations for Marty's return to 1985] Well, I guess that's everything.

Marty McFly: [pause] Thanks.

Dr. Emmett Brown: Thank *you*!

[Marty emotionally embraces Doc, which surprises him]

Dr. Emmett Brown: See you in about 30 years.

Marty McFly: I hope so.

[on the phone]

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

Dr. Emmett Brown: My equipment. That reminds me, Marty. You better not hook up to the amplifier. There's a slight possibility of overload.

Marty McFly: Yeah, I'll keep that in mind.

Marty McFly: He laid out Biff in one punch. I didn't know he had it in him. He's never stood up to Biff in his life!

Dr. Emmett Brown: [looks at the picture, realizing the implications of Marty's statement] Ever?

Dr. Emmett Brown: You've got to get your father and mother to interact in some sort of social...

Marty McFly: Wh-what? You mean like a date?

Dr. Emmett Brown: Right!

Marty McFly: What kind of date? I don't know. What do kids do in the '50s?

Dr. Emmett Brown: Well, they're your parents. You must know them. What are their common interests? What do they like to do together?

Marty McFly: Nothing.

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

Dr. Emmett Brown: [Doc Brown is trying to read Marty's mind with a geodesic helmet and a suction cup] Erm, you want me to make a donation to the Coastguard Youth Auxilliary?

Marty McFly: Doc,

[pulls off suction cup]

Marty McFly: 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.

Dr. Emmett Brown: My God. Do you know what this means?

[Significant pause]

Dr. Emmett Brown: It means that this damn thing doesn't work at all!

[Rips the helmet off]

Dr. Emmett Brown: I'm sure that in 1985, plutonium is available in every corner drugstore, but in 1955, it's a little hard to come by.

Dr. Emmett Brown: Things have certainly changed around *here*. I remember when this was all farmland as far the eye could see. Old man Peabody owned all of this. He had this crazy idea about breeding pine trees.

Dr. Emmett Brown: Oh, my God. They found me. I don't know how, but they found me. Run for it, Marty!

Marty McFly: Who? Who?

Dr. Emmett Brown: Who do you think? THE LIBYANS!

Marty McFly: HOLY SHIT!

Dr. Emmett Brown: You'll have to forgive the crudeness of this model. I didn't have time to paint it or build it to scale.

Dr. Emmett Brown: [the DeLorean has just made the first time-jump] Ah! What did I tell you? 88 miles per hour! The temporal displacement occurred exactly 1:20 a.m. and zero seconds!

Marty McFly: Ah, Jesus Christ! Jesus Christ, Doc, you disintegrated Einstein!

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

Marty McFly: Then where the hell are they?

Dr. Emmett Brown: 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.

Dr. Emmett Brown: You're late! Do you have no concept of time?

Marty McFly: Hey, come on. I had to change. Do you think I'm going back in that-that zoot suit? The old man really came through. It worked!

Dr. Emmett Brown: What?

Marty McFly: He laid out Biff in one punch. I didn't know he had it in him. He's never stood up to Biff in his life!

Dr. Emmett Brown: [looks at the restored picture, realizing the implications of what Marty just said] Ever?

Dr. Emmett Brown: Now, if my calculations are correct, when this baby hits 88 miles an hour, you're going to see some serious shit!
