Continuity mistake: When MacGruder is trying to find out where Hugh Palmer has hidden the log books, he sits on a chair and takes his glasses from their case. In the next shot, his glasses are already fully open and he is cleaning them with a cloth.
Continuity mistake: When Seagal is making a silencer out of a soda pop bottle, you see him tape the bottle completely to the gun, which would prevent him from taking a subsequent shot. After he fires through the window and comes through the door, the tape and bottle are completely gone and the gun is back to normal.
