Crap. I missed my own theme I suggested. Anyway, here is one example from TROY:

Messenger Boy: The Thessalonian you're fighting... he's the biggest man I've ever seen. I wouldn't want to fight him.

Achilles: That's why no-one will remember your name.

...and three from ZORBA THE GREEK:

Alexis Zorba: Damn it boss, I like you too much not to say it. You've got everything except one thing: madness! A man needs a little madness, or else...
Basil: Or else?
Alexis Zorba: ...he never dares cut the rope and be free.


Alexis Zorba: Why do the young die? Why does anybody die?
Basil: I don't know.
Alexis Zorba: What's the use of all your damn books if they can't answer that?
Basil: They tell me about the agony of men who can't answer questions like yours.
Alexis Zorba: I spit on this agony!


Basil: I don't want any trouble.
Alexis Zorba: Life is trouble. Only death is not. To be alive is to undo your belt and *look* for trouble.

...and one from THE LAST SAMURAI:

Katsumoto: You believe a man can change his destiny?
Algren: I think a man does what he can, until his destiny is revealed.
