Internal Affairs (1990)

Continuity mistake: When Richard Gere is driving through the city in his Corvette convertible, he starts with the top down, then you see the car with the hard top bolted on, then again without.

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.

Factual error: When officer Van is shot with a shotgun his body is lifted off the ground and knocked several feet backward. One of the basic laws of physics states for every action there is an equal and opposite reaction. The amount of energy required to lift and move an adult man would be tremendous and the person firing the gun would have been subjected to the same force.

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

Amy Wallace: You know all your friends from the force? You don't have them anymore.

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?

Amy Wallace: What Oakes said about your fellow officers respecting and honoring you is, as you probably know, complete crap. Most of the cops hate our guts. To the extent that they credit us with having any. They think we're climbers who went into I.A.D. for the promotions, which is true, not that we necessarily get them. So, they're polite because they're afraid of us. That's all.
