Continuity mistake: In the car chase scene, the escaped convict and police are exchanging gun fire between cars. In the different shots of the police car, the bullet holes in the windshield appear and disappear several times. Also, when three shots have been fired at the police car there are four bullet holes in the windshield.
Revealing mistake: During the car chase scene the cops shoot out the rear window of the convicts car, it is obvious that someone smashes the window with a hammer or crowbar from inside the car.(view in slow motion).
Other mistake: In the scene where Chris & Bill are about to bug Maria's phone, she is talking to her mom on the phone & Chris is on the telephone pole listening in. You can hear her talking but not her mom.
Continuity mistake: The convict's blue Pontiac changes between a '73 and a '74 model. The front grilles are a dead giveaway.
Continuity mistake: In the chase scene where the cops are chasing the convicts,Richard and Caylor, both taillights are shot out. When the car crashes into the river, both taillights are intact.
Continuity mistake: When Chris enters Maria's house in the guise of a telephone repairman, his partner informs him that she is in the bedroom tossing dirty clothes under the bed. She has to leave, and escorts him out, but when he sneaks back in, and is forced to hide under the bed when she returns unexpectedly, the clothes have vanished.
Visible crew/equipment: During the scene in the prison infirmary, the guard's nightstick is taken and used to beat the guard and the doctor. when it is first taken out of the guard's belt, it bends. Later, as it is being waved around, it can be seen bending repeatedly. It was obviously a rubber prop.
