Continuity: When Sylvester Stallone is asked why he couldn't join the NYPD, he points at his left ear and says it was because of deafness...but his deaf ear was the right.

Continuity: The first scene with Murray Babitch driving across the George Washington Bridge from New York to New Jersey was actually filmed going the other direction. When driving from New York to New Jersey on the lower level of the bridge you enter a black tunnel first, and exit through a yellow tiled tunnel. The scene in the film starts in the yellow tiled tunnel - New Jersey to New York direction.

Continuity: In one of the scenes, Stallone's character is playing a record. The music we hear is a song by Springsteen. However, the record doesn't have the red Columbia Records label that all of Springsteen's albums have. They obviously decided to use Springsteen's song later.

Continuity: There's a scene after supercop jumps from the bridge with a paramedic smoking a cigarette close to the butt. The camera switches and suddenly his cigarette is a freshly lit one.
