Leo G. Carroll credited as playing...
The Professor
- Roger Thornhill: I don't like the games you play, Professor.
- The Professor: War is hell, Mr. Thornhill. Even when it's a cold one.
- Roger Thornhill: If you fellows can't lick the VanDamm's of this world without asking girls like her to bed down with them and fly away with them and probably never come back, perhaps you ought to start learning how to lose a few cold wars.
- The Professor: I'm afraid we're already doing that.
- The Professor: If I thought there was any chance of changing your mind, I'd talk about Miss Kendall, of whom you so obviously disapprove.
- Roger Thornhill: Yes, for using sex like some people use a flyswatter.
- Roger Thornhill: You're police, aren't you? Or is it FBI?
- The Professor: FBI, CIA, ONI... we're all in the same alphabet soup.
