According to James Woods, his role in this film was one of his toughest because his character had to constantly be angry with Michael J. Fox's character, who he found very likeable in real life.

Early in the movie a car is released from a tow truck and it flips. The piston and the metal frame used to flip it are clearly visible during the flip and the subsequent roll of the car.

In addition to the usual cuts for broadcast standards, the version aired on NBC (and later on USA, etc.) showed scenes out of sequence. Just after John first meets Nick at the police station, the movie jumps to the two of them at the hot dog stand. After that entire scene plays out, it then goes back to the scene that would have originally preceded it, with John taking Nick to the ghetto to question the Dead Romeos. The re-edit probably would have been unnoticeable to a viewer if not for the fact that at the hot dog stand they are seen with a new, garish police car to replace one that was destroyed in the Dead Romeos scene.
