Continuity mistake: When Axel Foley hits Victor's hitman in the restaurant and the hitman lands on the buffet table, he has lots of stuff on his face and something green is stuck on his forehead. In the next shot, the hitman's face has been cleaned up a little and the green thing stuck on his forehead disappears.
Continuity mistake: When Axel and Mikey are at the bar Mikey puts his hand on Axel's neck. The shot changes and the hand is now on Axel's shoulder. The shot changes again and the hand is missing.
