Internal Affairs (1990)

Continuity mistake: When Dennis is talking to Raymond's wife at the restaurant, as he's watching from across the street, her hands under her chin change from one to both as the view changes from across the street to inside the restaurant.

Dennis Peck: How many cops you know, huh? Got nothing. Divorced, alcoholic, kids won't talk to them anymore, can't get it up. Sitting there in their little apartments, alone in the dark, playing lollipop with a service revolver?

Trivia: Richard Gere and Andy Garcia did not get along during the filming, and much of their fighting in the elevator sequence is real.
