Factual error: In the beginning of the movie, there is a scene where Joe Blake (Bruce Willis) confronts his teenage hostage, who has just found a shotgun in the home. Willis overwhelms the boy and takes the gun from him. When Willis empties the gun by sliding the pump action, the live shotgun shell falls to the bedroom floor. However, when the shell lands it sounds very much like an empty brass pistol case bouncing concrete. It happens again, later in the movie. Willis' character empties the same shotgun after shooting it into the ceiling during a bank robbery. The empty shotgun shell makes the identical sound when it hits the bank floor.
