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.
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.
