Clara Thornhill: You gentlemen aren't REALLY trying to kill my son, are you?

- Jessie Royce Landis (as Clara Thornhill) in North by Northwest (1959)

Leonard: You must have had some doubts about her yourself. You still do.
Phillip Vandamm: Rubbish.
Leonard: Why else would you have decided not to tell her that our little treasure here has a belly full of microfilm?
Phillip Vandamm: You seem to be trying to fill mine with rotten apples.
Leonard: Sometimes the truth does taste like a mouthful of worms.
Phillip Vandamm: The truth? I've heard nothing but innuendos.
Leonard: Call it my woman's intuition, if you will. But I've never trusted neatness. Neatness is always the result of deliberate planning.

- Martin Landau (as Leonard) in North by Northwest (1959)

Leonard: You're not taking her on the plane with you?
Phillip Vandamm: Of course I am. Like our friends, I too believe in neatness, Leonard. This matter is best disposed of from a great height, over water.

- James Mason (as Phillip Vandamm) in North by Northwest (1959)

Man at Prairie Crossing: That's funny, that plane's dustin' crops where there ain't no crops.

Roger Thornhill: Yes, for using sex like some people use a flyswatter.

Roger Thornhill: [to Eve] Who are you kidding? You have no feelings to hurt.

Roger Thornhill: And what the devil is all this about? Why was I brought here?
Phillip Vandamm: Games? Must we?
Roger Thornhill: Not that I mind a slight case of abduction now and then, but I have tickets for the theater this evening, to a show I was looking forward to and I get, well, kind of *unreasonable* about things like that.
Phillip Vandamm: With such expert playacting, you make this very room a theater.

- James Mason (as Phillip Vandamm) in North by Northwest (1959)

Roger Thornhill: Apparently the only performance that will satisfy you is when I play dead.
Phillip Vandamm: Your very next role, and you'll be quite convincing, I assure you.

- James Mason (as Phillip Vandamm) in North by Northwest (1959)

Roger Thornhill: Handle with care, fellas. I'm valuable property.

- Cary Grant (as Roger O. Thornhill) in North by Northwest (1959)

Roger Thornhill: How does a girl like you get to be a girl like you?
Eve Kendall: Lucky, I guess.
