Plot hole: The film was made in 1988. At that time the airport was on the mainland Kowloon side and called Kai Tak. In the early part of the film where van Damme is heading for the "East Lake Hotel" in Kowloon he is seen riding on an electric tram. These trams are only found on Hong Kong Island, which means he would have had to have crossed the harbour to reach the trams and then gone back across the harbour to reach his hotel. Fairly pointless exercise.

Continuity mistake: When Frank and Jackson first meet Mr.Lin in the hotel he has a little moustache, goatee, and some sideburns, as much as he can grow anyway. Then they start to walk to the Kumite arena. When they get to the entrance to the corridor, he still has his facial hair when the guy says "OK USA!" But, when they actually enter the arena for the Kumite, he's completely shaven.
Other mistake: During the second day of fighting, fights are shot out of order. For example, When Chong Li and Suan Paredes fight, the (fighters) benches are nearly empty (the one on the right is empty aside from Chong Li's assistant), but in several fights following, they are more than half full. In fact, Paredes can be seen sitting on his bench in shots after Chong Li snaps his leg in half.
