Bullitt: Look, Chalmers, let's understand each other... I don't like you.

Bullitt: Look, you work your side of the street, and I'll work mine.

Bullitt: You sell whatever you want, but don't sell it here tonight.

Cathy: What will happen to us, in time?
Bullitt: Time starts now.

[Bullitt and Delgetti have searched the luggage of Dorothy Simmons and her boyfriend]
Delgetti: No passports, no tickets.
Bullitt: Call Immigration in Chicago, have them wire Rennick's passport application, I'll get a fingerprint check on Ross.

Bullitt: [revealing Johnny Ross' death] I've got him downstairs, under a John Doe.
Baker: [stunned] You are sick. Smuggling a dead man out of a hospital, and now two men killed who may have had nothing to do with it?
Bullitt: The man I was chasing killed Ross.
Captain Bennett: How do you know? Did you see him?
Bullitt: Yes. He tried to nail me with a shotgun, a Winchester pump.
Baker: The radio report said the two men were burned beyond recognition. Now all he's got are two dead men. It would never hold up in court.
