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.

Directed by: Mike Figgis
Starring: Richard Gere, Andy Garcia, Nancy Travis, Laurie Metcalf
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.
Amy Wallace: You know all your friends from the force? You don't have them anymore.
Trivia: Richard Gere and Andy Garcia did not get along during the filming, and much of their fighting in the elevator sequence is real.
