Jefferson Smith: Dad always used to say the only causes worth fighting for were the lost causes.

Rhett Butler: I believe in Rhett Butler, he's the only cause I know.

'Kit Carson' Holliday:Jeb, I'm frightened. That boy is crippled for life. And that man on the train, he died for a principle. A man killed for a principle. One of them is wrong, but which one?

Rick: Don't you sometimes wonder if it's worth all this? I mean what you're fighting for.
Victor Laszlo: You might as well question why we breathe. If we stop breathing, we'll die. If we stop fighting our enemies, the world will die.
Rick: Well, what of it? It'll be out of its misery.
Victor Laszlo: You know how you sound, Mr. Blaine? Like a man who's trying to convince himself of something he doesn't believe in his heart.

Scarlett: But you are a blockade runner.
Rhett Butler: For profit, and profit only.

The noblest thoughts that ever flowed through the hearts of men are contained in its extraordinary, imaginative, and musical mixtures of sounds. And that's what you've set yourself out to conquer Eliza. And conquer it you will.

Carol Beldon: I know how comfortable it is to curl up with a nice, fat book full of big words and think you're going to solve all the problems in the universe. But you're not, you know. A bit of action is required every now and then.

Prince Feisal: But you know, Lieutenant, in the Arab city of Cordoba were two miles of public lighting in the streets when London was a village?
T.E. Lawrence: Yes, you were great.
Prince Feisal: Nine centuries ago.
T.E. Lawrence: Time to be great again, my lord.

Mrs. Green: You think there's enough anti-Semitism in life already without people reading about it?
Phil Green: No, but this story is doomed before I start. What can I say about anti-Semitism that hasn't been said before?
Mrs. Green: Maybe it hasn't been said well enough. If it had, you wouldn't have had to explain it to Tommy right now.
