Frank Dux

Frank William Dux, born on April 6, 1956, is a prominent Canadian-American martial artist, choreographer, and author. Dux claims to have been trained in ninjutsu by a master named Senzo Tanaka during his teenage years. He later founded his own style known as Dux Ryu Ninjutsu. In 1975, he purportedly won a clandestine martial arts competition called the Kumite, a claim that has sparked controversy and skepticism regarding both the tournament's legitimacy and Tanaka's existence. His narrative about the Kumite notably inspired the 1988 film "Bloodsport," featuring Jean-Claude Van Damme.

In addition to his martial arts pursuits, Dux made his mark in the film industry as a fight choreographer on projects such as "Bloodsport," "Lionheart" (1990), and "Only the Strong" (1993). He also authored "The Secret Man" in 1996, where he recounted his alleged covert operations for the CIA. That same year, he collaborated with Van Damme on the screenplay for "The Quest," although their partnership ended in legal disputes, including a breach of contract lawsuit that Dux lost in 1998. Furthermore, he faced a libel suit against "Soldier of Fortune" magazine in 1999, which questioned his military credentials and CIA claims. Despite the controversies surrounding his career, Dux remains a notable figure in martial arts and film choreography.
