Frank Dux (pronounced "dukes") is a martial artist and fight choreographer. Dux established his own school of Ninjutsu in 1975, called "Dux Ryu Ninjutsu". An article about his purported exploits, which appeared in Black Belt in 1980, was the eventual inspiration for the 1988 film Bloodsport starring Jean-Claude Van Damme.[1]

Martial arts career[edit]

Dux states that he was introduced to and trained in Koga Yamabushi Ninjutsu by Senzo Tanaka.[2] Dux's martial art style, Dux Ryu Ninjitsu, is not a koryu (15th century feudal form of Ninjutsu), but is still claimed[by whom?] to be "based on its Koga Ninja root principles of adaptability and consistent change".[2] Frank Dux taught a technique he calls DUX FASST (Focus-Action-Skill-Strategy-Tactics).

The accuracy of many of Dux's personal claims has been disputed, including his martial arts background, fighting in the "Kumite", and prior military service. According to the Los Angeles Times, the organization that allegedly staged the Kumite had the same address as Dux's house, and the trophy he claims to have won was bought by him at a local trophy store.[3] This was disputed by Dux, who claimed that the receipt was fabricated. He also claims that his critics are part of a conspiracy to discredit him, led by ninjutsu master Stephen K. Hayes, whom Dux claims views him as a threat.[4][5]

In 2012 Sheldon Lettich, co-writer of the film Bloodsport based on Dux's "Kumite" claims, dismissed those claims and others Dux had made as being completely false.[6]

Film Credits[edit]

Dux's credits on martial arts films are as follows:

  • 1993 Only the Strong (fight choreographer) (additional thanks)[7]
  • 1990 Lionheart (fight choreographer) / (fight trainer)[citation needed]


Dux has written a 1996 autobiography entitled The Secret Man: An American Warrior's Uncensored Story. Dux's story was the inspiration for the 1988 motion picture, Bloodsport, which he choreographed.[8][9] Jean-Claude Van Damme starred in this motion picture. Dux is also credited as a story co-author for the film The Quest.[10][11]
