Brandon Shaw: Determined to get drunk, aren't you?
Phillip Morgan: I am drunk.
Brandon Shaw: And just as childish as you were before when you called me a liar.
Phillip Morgan: You had no business telling that story.
Brandon Shaw: Why did you lie anyway?
Phillip Morgan: I had to! Have you ever bothered for just one minute to understand how someone else might feel?
Brandon Shaw: I'm not sentimental if that's what you...
Phillip Morgan: No, that's not what I mean; but it doesn't matter. Nothing matters... except that Mr. Brandon liked the party. Mr. Brandon gave the party. Mr. Brandon had a delightful evening. Well, I had a rotten evening!
Brandon Shaw: Keep drinking, and you'll have a worse morning.
Phillip Morgan: At least if I have a hangover, it'll be all mine!

Brandon Shaw: Good and evil, right and wrong were invented for the ordinary average man, the inferior man, because he needs them.

Brandon Shaw: I've always thought that it was out of character for David to drink anything as corrupt as Whiskey.
Phillip Morgan: Out of character for him to be murdered, too.

Brandon Shaw: Mrs. Wilson, champagne!
Kenneth: Oh, it isn't someone's birthday is it?
Brandon Shaw: Don't look so worried, Kenneth. It's, uh, really almost the opposite.

Brandon Shaw: Of course, he was a Harvard graduate. That might be grounds for justifiable homicide.

Brandon: [David screams, to Phillip] Open it.
[they put David in the trunk and close it]

Brandon: I've always wished for more artistic talent. Well, murder can be an art, too. The power to kill can be just as satisfying as the power to create.

Brandon: Nobody commits a murder just for the experiment of committing it. Nobody except us.

Brandon: We killed for the sake of danger and for the sake of killing.

Rupert Cadell: [Phillip and Brandon have been arguing about strangling chickens] Personally, I think a chicken is as good a reason for murder as a blonde, a mattress full of dollar bills or any of the customary, unimaginative reasons.
Janet Walker: Well, now, you don't really approve of murder, Rupert? If I may?
Rupert Cadell: You may... and I do. Think of the problems it would solve: unemployment, poverty, standing in line for theatre tickets...
