Rick: I'm saying it because it's true. Inside of us, we both know you belong with Victor. You're part of his work, the thing that keeps him going. If that plane leaves the ground and you're not with him, you'll regret it. Maybe not today. Maybe not tomorrow, but soon and for the rest of your life.
Ilsa: But what about us?
Rick: We'll always have Paris. We didn't have, we, we lost it until you came to Casablanca. We got it back last night.
Ilsa: When I said I would never leave you.
Rick: And you never will. But I've got a job to do, too. Where I'm going, you can't follow. What I've got to do, you can't be any part of. Ilsa, I'm no good at being noble, but it doesn't take much to see that the problems of three little people don't amount to a hill of beans in this crazy world. Someday you'll understand that. Now, now... Here's looking at you kid.
Captain Renault: Carl, see that Major Strasser gets a good table, one close to the ladies.
Carl: I have already given him the best, knowing he is German and would take it anyway.
Major Strasser: Are you one of those people who cannot imagine the Germans in their beloved Paris?
Rick: It's not particularly my beloved Paris.
Heinz: Can you imagine us in London?
Rick: When you get there, ask me!
Captain Renault: Hmmh! Diplomatist!
Major Strasser: How about New York?
Rick: Well there are certain sections of New York, Major, that I wouldn't advise you to try to invade.
[Last line, as Rick and Captain Louis Renault walk off.]
Rick: Louis, I think this is the beginning of a beautiful friendship.
Rick: Of all the gin joints, in all the towns, in all the world, she walks into mine.
Ilsa: Play it once, Sam. For old times' sake.
Sam: [lying.] I don't know what you mean, Miss Elsa.
Ilsa: Play it, Sam. Play "As Time Goes By."
Sam: [lying.] Oh, I can't remember it, Miss Elsa. I'm a little rusty on it.
Ilsa: I'll hum it for you. Da.dee.da.dee.da.dum, da.dee.da.dee.da.dum...
[Sam begins playing on the piano.]
Ilsa: Sing it, Sam.
Sam: [singing.] You must remember this / A kiss is still a kiss / A sigh is just a sigh / The fundamental things apply / As time goes by. / And when two lovers woo, / They still say, "I love you" / On that you can rely / No matter what the future brings...
Rick: [rushing up.] Sam, I thought I told you never to play...
[Rick sees Ilsa. Sam closes the piano and rolls it away.].
Rick: Here's lookin' at you, kid.
