Peter Lorre as Joel Cairo: "I thought and hoped you could assist me."

Sydney Greenstreet as Kasper Gutman: "That's an attitude, sir, that calls for the most delicate judgment on both sides, because as you know, sir, in the heat of action, men are likely to forget where their best interests lie and let their emotions carry them away."

Sydney Greenstreet: "Ha, ha, ha, ha, ha! My God, sir, you are a character – that you are! There's never any telling what you'll say or do next."

Humphrey Bogart as Sam Spade: "You've got to convince me that you know what this is all about, that you aren't just fiddling around, hoping that it'll all come out right in the end!"

Sydney Greenstreet: "You certainly are a most headstrong individual."

Peter Lorre: "You imbecile!! You bloated idiot!!"

Peter Lorre: "You seem to forget that you are not in a position at all to insist upon anything!

Bogart: "No, that'll be all. Just be sure to lock the door behind you on your way out. Good night."

Bogart: "This won't do any good."

Humphrey Bogart: "When a man's partner is killed, he's supposed to do something about it. It doesn't make any difference what you thought of him. He was your partner and you're supposed to do something about it."

Bogart: "When you're slapped, you'll take it and like it!"

Ward Bond as Detective Tom Polhaus: "It's heavy. What is it?"

Humphrey Bogart: "The, uh, stuff that dreams are made of."

Humphrey Bogart: "You're taking the fall."

Sydney Greenstreet: "Here's to plain speaking and clear understanding... You're a closed-mouth man?"

Humphrey Bogart: "No, I like to talk."

Greenstreet: "Better and better. I distrust a closed-mouth man. He generally picks the wrong time to talk and says the wrong things. Talking's something you can't do judiciously unless you keep in practice... Now, then, we'll talk if you like. I tell you right out I am a man who likes talking to a man who likes to talk."

Sydney Greenstreet: "I do like a man who tells you right out he's lookin' out for himself. Don't we all? I don't trust a man who says he's not."

Humphrey Bogart: "Well?... I wanna know about this."
