THE MALTESE FALCON (1941)

Wilmer Cook (Elisha Cook, Jr.): "Keep on riding me, Spade, and they're gonna be picking iron out of your liver."
Sam Spade (Humphrey Bogart): "The cheaper the crook, the gaudier the patter, eh?"

Mary Astor: “Mr. Archer was so alive yesterday, so solid and hearty.”
Spade: “Stop it! He knew what he was doing. Those are the chances we take."
Astor: "Was he married?”
Spade: “Yeah, with ten thousand insurance, no children, and a wife that didn't like him.”

Cop, picking up the falcon: “Heavy. What is it?”
Spade: “The, uh, stuff that dreams are made of.”
