Frank Dux is a martial art professional, author, entrepreneur, and fight choreographer. He has also served in the ‘United States Marine Corps Reserve’ from 1975 to 1981. He claims to have gone on various secret missions for the US and even worked for ‘Central Intelligence Agency’ aka ‘CIA.’ He even reckons to have won the ‘Medal of Honor’ from the US army. However, none of his military records confirm his claims. The alleged claim has been mentioned in his book ‘The Secret Man’ (1996). Many authors have accused him of fabricating the facts of his military service. He made his debut as a fight choreographer in the 1988 film ‘Blood Sport.’ His other film credits include ‘Lionheart’ (1990), and ‘Only the Strong’ (1993). He also co-wrote the 1996 film ‘The Quest’ alongside Jean-Claude Van Damme. He later sued Van Damme for breach of contract over the aforementioned film, and lost the suit in 1998.
