Continuity mistake: When RJ sits on Jason's midriff he is eating a Popsicle with chocolate on it but in the next shot the chocolate its completely gone. (01:05:30)
Other mistake: Van Damme in the opening credits is presented quite literally as "Ivan, the Russian." During the movie they call him Ivan and is last name in the tournament is mentioned by the announcer as "Krasinki." So naturally in the end credits roll Van Damme is billed as... Karl Brezdin. Close.
