Deliberate mistake: When Jack rips the door off the cab, he first breaks the top hinge and enters the cab. In the next shot when he pulls the cabbie out of the car, the door is completely off and laying on the ground. A few shots later when Jack grabs the newspaper, the door is seen hanging again.
Question: All of the actors in this film are actually credited as either themselves, or their character in the Jack Slater films (eg. the reporters recognise Tom Noonan as himself at the film premiere). However, the actress playing Whitney is actually called Bridgette Wilson, not Meredeth as Danny points out. Why was this?
