The Maltese Falcon1941

Spade:
If you kill me, how are you gonna get the bird? And if I know you can't afford to kill me, how are you gonna scare me into giving it to you?

Gutman:
Well, sir, there are other means of persuasion besides killing and threatening to kill.

Spade:
Yes, that's, that's true. But - they're none of 'em any good unless the threat of death is behind them - do you see what I mean? If you start something, I'll make it a matter of your having to kill me or call it off.

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

Spade:
Then the trick from my angle is to make my play strong enough to tie you up, but not make you mad enough to bump me off against your better judgment.

Gutman:
By gad, sir, you are a character.

[Cairo whispers into Gutman's ear]

Spade:
[To Wilmer] Six, two and even, they're selling you out, sonny. [To Gutman] I hope you're not letting yourself be influenced by the guns these pocket-edition desperados are waving around, because I've practiced taking guns away from these boys before so we'll have no trouble there.
