Stunt coordinator and fight choreographer for this movie was Frank Dux - the full-contact martial artist whose life was portrayed by Jean-Claude Van Damme in the movie Bloodsport (1988). Moreover, Dux has a cameo appearance as one of the men fighting Louis Stevens in the car workshop.
The fighting style Capoeira was invented by African slaves who were sent to Brazil in the early 16th century. The dance moves that the style is centered around, were incorporated in order to hide the intention of learning to fight, from the slave masters.
Mark Dacascos was born into martial arts, each of his parents renowned martial artists who created their own style (father, Al Dacascos-Won Hop Kuen Do; mother, Malia Bernal-Xiang Dai Kuen Kung Fu). He went on to star in the television version of "The Crow," a movie that started another born into martial arts: Brandon Lee, son of Jeet Kune Do founder Bruce Lee.
Director Sheldon Lettich was not satisfied with the movie's fight content, claiming years later in Put Up Your Dux (2010) that fight choreographer Frank Dux did not deliver as creative of martial arts scenes as he had conceptualized.
