A young American studying in Paris in 1968 strikes up a friendship with a French brother and sister. Set against the background of the '68 Paris student riots.

Matthew: Yes, I'm drunk. And you're beautiful. And tomorrow morning, I'll be sober but you'll still be beautiful.
Father: Listen to me, Theo. Before you can change the world you must realize that you, yourself, are part of it. You can't stand outside looking in.
Matthew: I don't believe in God, but if I did, he would be a black, left-handed guitarist.
Theo: Papa's full of shit.
Matthew: I think you're lucky. I wish my parents were that nice.
Isabelle: Other people's parents are always nicer than our own, and yet for some reason, our grandparents are always nicer than other people's.
Isabelle: We do love you very much!
Matthew: I don't want to be loved very much, I just want to be loved.
Matthew: I was one of the insatiables. The ones you'd always find sitting closest to the screen. Why do we sit so close? Maybe it was because we wanted to receive the images first. When they were still new, still fresh. Before they cleared the hurdles of the rows behind us. Before they'd been relayed back from row to row, spectator to spectator; until worn out, secondhand, the size of a postage stamp, it returned to the projectionist's cabin. Maybe, too, the screen was really a screen. It screened us... from the world.
Isabelle: Oh, Matthew. How nice of you to keep my image close to your heart.
Matthew: I think you prefer when the world "together" means not "a million," but just two.
[first lines]
Matthew: The first time I saw a movie at the cinématèque française I thought, "Only the French... only the French would house a cinema inside a palace."
Matthew: In this big, epic movie - everyone is an extra.
Matthew: I could hear my heart pounding. I don't know if it was because I'd just been chased by the police or because I was already in love with my new friends.
Matthew: [about Theo] Has he never been inside of you?
Isabelle: He's always inside of me.
Matthew: I wish you could step out of yourself and just look.
Matthew: I thought you had many lovers. I mean when I saw you for the first time, at the Cinématheque, you and Theo, you looked so cool, so sophisticated. Like a movie star.
Isabelle: I was. I was acting, Matthew
Isabelle: My parents fucked once in their lives. That's why we're twins, they didn't want to make it twice.
Matthew: This is not Chaplin and Keaton. This is Clapton and Hendrix.
Theo: Matthew, Clapton reinvented the electric guitar.
Matthew: Clapton plugs in a guitar, he plugs in an electric guitar and he plays it like an acoustic guitar. Hendrix plugs in an electric guitar, he plays it with his teeth. There are soldiers in the Vietnam War right now. Who are they listening to? Clapton? No, they're listening to Hendrix. The guy who tells the truth.
Isabelle, Theo: We accept you, one of us! One of us!
Isabelle: [while posing as the Venus de Milo] I can't stop you, I've got no arms.
Matthew: As we walked, we talked and talked and talked about politics, about movies, and about why the French could never come close to producing a good rock band.
Theo: [reading from a book] A revolution isn't a gala dinner. It cannot be created like a book, a drawing or a tapestry. It cannot unfold with such elegance, tranquility and delicacy. Or such sweetness, affability. Courtesy, restraint and generosity. A revolution is an uprising, a violent act by which one class overthrows another.
Isabelle: I entered this world on the Champs-Elysees, 1959. La trottoir du Champs Elysees. And do you know what my very first words were? New York Herald Tribune! New York Herald Tribune!
Isabelle: Theo, Theo. Wake up.
Theo: [sleepily, eyes still closed] What is it?
Isabelle: I want you to listen.
Theo: Why?
Isabelle: Because. Theo?
Theo: Mm?
Isabelle: I love you. You know that?
Theo: I love you too.
Isabelle: You love me too? That's funny. Are you listening? It's forever, right?
Theo: What's forever?
Isabelle: The two of us. Right?
Theo: Yes. Why did Matthew say that?
Isabelle: What did Matthew say?
Theo: That we're monsters, freaks.
Isabelle: I just want you to tell me that it's forever. It's forever.
Isabelle: Pom pom, pom pom pom, turu turururu pom pom pom
[Matthew has had unprotected sex with Isabelle]
Matthew: [in the tub, he sees blood]
Isabelle: Don't be alarmed. It's good news.
Theo: It only happens once a month.
[last lines]
Matthew: Listen to me for a second, okay? This is what they do. This is not what we do.
Matthew: [pointing to his head] We use this.
Matthew: We do this. We use this.
[kisses Isabelle]
Matthew: We use this.
[kisses Theo]
Theo: [speaking in French] Stop it!
Matthew: Isabelle. Come on. Isabe...
Matthew: It makes films like crimes, and directors like criminals.
Matthew: Yes, I'm drunk. And you're beautiful. And tomorrow morning, I'll be sober but you'll still be beautiful.
Isabelle: This is a test.
Matthew: It's fucked up. It's all fucked up.
Theo: [to Matthew] Don't forget your toothbrush!
Theo: Weren't you just a tiny bit excited?
Isabelle: Name a film where someone tap dancing drives someone else crazy!
Matthew: Oh, I know this!
Isabelle: Come on! Quick! Quick!
Matthew: Top Hat! Top Hat! Fred Astaire's dancing over Ginger Roger's room. And she's mad because he wakes her up. I'm right.
