Coup dur

Hong Kong superstar and director Sammo Kam-Bo Hung served as the film's 2nd unit director. The release print of "Knock Off" suffers from the removal of a lot of the martial arts action shot for the film, with a couple of sequences being very heavily edited. The final battle between Jean-Claude Van Damme's character and Australian actor/stuntman Michael Miller is less than half of the action shot for their fight, and upon careful viewing you can pick up the fact that the fight has raged across several different sections on the boat, while the fight between Jeff Wolfe's character Scar and Jean-Claude's is the most heavily edited with more of the action being shown in the "Making Of" featured on several of the DVD editions than in the finished film.

At the beginning, the dead guy that flew out of the boat,uses his own hand to push himself over as he is being kicked to turn over.
