David Bradley (born Bradley Simpson in Texas, 2 October, 1956) is an American actor and martial artist, known for starring in numerous low-budget action movies beginning in the late 1980s. His best-known films are the American Ninja sequels.
Bradley is known for his role as Sean Davidson in American Ninja 3: Blood Hunt and American Ninja 4: The Annihilation. He also stars in a separate film titled, American Ninja V, as Joe Kastle, which is not technically a sequel to the previous American Ninja films, but a different movie altogether. Previous to making films, Bradley worked as care salesman on Wilshire Boulevard. He attended the screening of American Ninja 3: Blood Hunt in Los Angeles, and director Cedric Sundstrom claimed that he in Bradley found a good balance between vulnerability and physical aspects. According to Sundstrom, Bradley always resented the fact that his character got rescued by Michael Dudikoff's character in the film American Ninja 4: The Annihilation.
Bradley is trained in Karate (black belt), Shotokan, Kempo, Tai Chi, and Aikido.
