Donnie Darko 
- [in a letter] Dear Roberta Sparrow, I've reached the end of your book and there are so many questions that I need to ask you. Sometimes I am afraid of what you might tell me. Sometimes I am afraid this is not a work of fiction. I can only hope that the answers will come to me in my sleep. I hope that when the world comes to an end, I can breathe a sigh of relief, because there will be so much to look forward to.
- You're right, actually. I am pretty- I'm, I'm pretty troubled and I'm, I'm pretty confused. But I... and I'm afraid. Really, really afraid. Really afraid. But I... I... I think you're the fucking Antichrist.
Dr. Thurman 
- If the sky were to suddenly open up... there would be no law... there would be no rule. There would only be you and your memories... the choices you've made and the people you've touched. The life that has been carved out from your subconscious is the only evidence by which you will be judged... by which you must judge yourself. Because when this world ends, there will only be you and him... and no one else.
- How did you feel being denied these 'Hungry Hungry Hippos'?
Gretchen Ross 
- Some people are just born with tragedy in their blood.
- What if you could go back in time and take all those hours of pain and darkness and replace them with something better?
Kitty Farmer 
- Okay, now girls... I want you to concentrate. Failure is not an option. And Bethany, if you feel the need to vomit up there... just swallow it.
Roberta Sparrow 
- Every living creature on this earth dies alone.
- Elizabeth: You can go suck a fuck!
- Donnie: Oh, please, tell me, Elizabeth, how exactly does one suck a fuck?
- Gretchen Ross: Donnie Darko? What the hell kind of name is that? It's like some sort of superhero or something.
- Donnie: What makes you think I'm not?
- Gretchen: You're weird.
- Donnie: Sorry.
- Gretchen: No, that was a compliment.
- Gretchen: My mom had to get a restraining order against my stepdad. He has emotional problems.
- Donnie: Oh, I have those too! What kind of emotional problems does your dad have?
- Gretchen: He stabbed my mom four times in the chest.
- Donnie: Oh.
- Sean Smith: Beer and pussy. That's all I need.
- Ronald Fisher: Well we gotta find ourselves a Smurfette.
- Sean Smith: Smurfette?
- Ronald Fisher: Mmm-hmm [gulps beer]. Not some like tight-ass Middlesex chick, y'know? Like this cute little blonde that'll get down and dirty with the guys. Like Smurfette does.
- Sean Smith: [nods agreement] Hmm.
- Donnie: Smurfette doesn't fuck.
- Ronald Fisher: That's bullshit. Smurfette fucks all the other Smurfs. Why do you think Papa Smurf made her? It's because all the other Smurfs were getting too horny.
- Sean Smith: No, no, no, not Vanity. I heard he was a homosexual.
- Ronald Fisher: Okay well you know what then, she fucks them while Vanity watches, okay?
- Sean Smith: Well what about Papa Smurf? I mean, he must get into all the action.
- Ronald Fisher: Yeah. What he does: He films the gangbang, later on...he beats off to the tape.
- Donnie: [earnestly] First of all: Papa Smurf didn't create Smurfette - Gargamel did! She was sent in as Gargamel's evil spy with the intention of destroying the Smurf village. But the overwhelming goodness of the Smurf way of life transformed her. And as for the whole gangbang scenario - Huh! I - it just couldn't happen. Smurfs are asexual, th-they don't even have... reproductive organs under those little... white... pants. That's what's so illogical, y'know, about being a Smurf. Y'know what's the point of living... if you don't have a dick?
- Sean Smith: [sighs] Dammit, Donnie, wh-why you gotta get so smart on us?
- [Donnie tries to kiss Gretchen and she pulls away.]
- Donnie: Well I-I, sorry I...
- Gretchen: Donnie wait...
- Donnie: I like you a lot...
- Gretchen: I just want it to be... at a time when... it...
- Donnie: When what?
- Gretchen: When it reminds me just...
- Donnie: When it reminds you of how beautiful the world can be?
- Gretchen: Yeah... [turns her head] and right now there's some fat guy over there staring at us.
- Donnie: Good morning.
- Jim Cunningham: Good morning.
- Donnie: Um... how much are they paying you to be here?
- Jim Cunningham: Uh, excuse me? What is your name, son?
- Donnie: Gerard.
- Jim Cunningham: Gerald, I think you're afraid.
- Donnie: Are you telling us this stuff so we can buy your book because, I gotta tell ya, if you are, that was some of the worst advice I ever heard.
- Jim Cunningham: You see how sad this is-
- Donnie: You want your sister to lose weight? Tell her to get off the couch, stop eating Twinkies and maybe go out for field hockey. You know what? No one ever knows what they want to be when they grow up. You know, it takes a little- little while to find that out. Right, Jim? And you. Yeah, you. Sick of some jerk shoving your head down the toilet? Well, you know what? Maybe you should lift some weights or, uh, take a karate lesson. And the next time he tries to do it, you kick him in the balls!
- Jim Cunningham: [laughs] Son... do you see this?
- Donnie: Right?
- Jim Cunningham: This is an anger prisoner. A textbook example.
- Donnie: Anger prisoner.
- Jim Cunningham: Do you see the fear, people? This boy is scared to death of the truth. Son, it breaks my heart to say this, but I believe you are a very troubled and confused young man. I believe you are searching for the answers in all the wrong places.
- Donnie: You're right, actually. I am pretty- I'm pretty troubled and I'm pretty confused, but I... And I'm afraid. Really, really afraid. Really afraid. But I- I think you're the fucking Antichrist.
- Donnie Darko: Why do you wear that stupid bunny suit?
- Frank: Why are you wearing that stupid man suit?
- Dr. Lillian Thurman: Do you feel alone right now?
- Donnie: I... I don't know... I mean, I'd like to believe that I'm not, but I just... I've just never seen any proof, so I... I just don't debate it anymore. You know, it's like I could spend my whole life debating it over and over again, weighting the pro's and con's and in the end, I still wouldn't have any proof, so I just... I just don't debate it anymore. Heh, it's absurd...
- Dr. Thurman: The search for God is absurd?
- Donnie: It is if everyone dies alone.
- Dr. Thurman: Does that scare you?
- Donnie: I don't wanna be alone.
- Life is one long insane trip. Some people just have better directions.
- You can never go too far.
- What would you do if you knew the future?
- Be Afraid of the Dark.
- Dark. Darker. Darko.
- Why are you wearing that stupid man suit?
- Why are you looking at me?
- The only way to unwind the future is to follow the path.
- Cellar Door.
- They Made Me Do It.
