Rick: How can you close me up? On what grounds?
Captain Renault: I'm shocked, shocked to find that gambling is going on in here!
[a croupier hands Renault a pile of money]
Croupier: Your winnings, sir.
Captain Renault: [sotto voce] Oh, thank you very much.

Captain Renault: [aloud] Everybody out at once!

Rick: I congratulate you.
Victor Laszlo: What for?
Rick: Your work.
Victor Laszlo: I try.
Rick: We all "try"; You succeed!

Rick: I stick my neck out for nobody!

Rick: If it's December 1941 in Casablanca, what time is it in New York?
Sam: What? My watch stopped.
Rick: I'd bet they're asleep in New York. I'd bet they're asleep all over America.

Rick: Last night we said a great many things. You said I was to do the thinking for both of us. Well, I've done a lot of it since then, and it all adds up to one thing: you're getting on that plane with Victor where you belong.
Ilsa: But, Richard, no, I... I...
Rick: Now, you've got to listen to me! You have any idea what you'd have to look forward to if you stayed here? Nine chances out of ten, we'd both wind up in a concentration camp. Isn't that true, Louie?
Captain Renault: I'm afraid Major Strasser would insist.
Ilsa: You're saying this only to make me go.
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.

Rick: Of all the gin joints, in all the towns, in all the world, she walks into mine.

Rick: Who are you really, and what were you before? What did you do and what did you think, huh?
Ilsa: We said no questions.
Rick: ...Here's looking at you, kid.

Rick: You'll excuse me, gentlemen. Your business is politics, mine is running a saloon.

Rick: Well, I guess neither one of our stories is very funny. Tell me, who was it you left me for? Was it Laszlo, or were there others in between? Or - aren't you the kind that tells?

Ugarte: You despise me, don't you?
Rick: If I gave you any thought I probably would.
