William Duen Wai-Lun
Born 1958 · Hong Kong, British Crown Colony
William Duen Wai-lun, born 1958, was a one of the real life bodyguards of Jackie Chan along with Jackie Chan Stunt Team member Ken Lo, a role he performed from 1988 to 2003. He worked on many films with Jackie Chan and his stunt team and even did a few stunts himself. He was known more as a character actor than a stuntman, often playing police officials, including controversially in the movie High Risk (1995), which mocked Jackie Chan. In the movie Gorgeous (1999) he and fellow Jackie Chan bodyguard, Ken Lo, parody their real selves by playing bodyguards to the films antagonist L. W. Lo, played by Emil Chau.
