Bloodsport

The Bloodsport franchise consists of American martial arts-sports action-thriller installments including two theatrical films, two straight-to-home video sequels, and one limited release reimagined genderswap-followup. Based on the purported true story experiences of Frank Dux, which have since been called into question, the series centers around the original story written by Sheldon Lettich. The plot involves American characters who compete in underground life-or-death mixed martial arts tournaments, while also competing for the honor of their instructors.
