Continuity mistake: During the skeleton attack by the locked gate, at the bottom of the gate, there are sandbags that disappear and reappear between scenes. Possibly there to stabilize the gate when Johnny flies into it.
Continuity mistake: After the Halloween fight, none of the Cobras injures the next day match what happened to them the night before. Johnny had a black eye although he was only flipped and chopped in the chest. Tommy had his arm in a sling, but he was kicked twice in the stomach.
Other mistake: In the semi final match between Johnny and Duval his name is listed behind them on the board as Vidal. But you can hear him being announced as Duval.
Suggested correction: He doesn't say "Duval", he says "Darryl Vidal." While the character isn't listed by name in the credits, only listed as "Karate Semi-finalist", he was in fact played by Darryl Vidal, who was an actual black belt at the time of the movie.
