Biography: A native of Toronto, Ontario, fair-haired actress Katheryn Winnick began her movie career behind the camera, as a martial arts trainer for the stars. (She earned dual black belts in tae kwon do and karate, and received her bodyguard license at an early age.) Winnick soon parlayed her glamorous countenance into acting, but expressed a highly vocal interest in challenging and demanding roles, and resisted being pigeonholed as simply a pretty face. Audiences first gained exposure to Winnick on television, with her involvement in such series as PSI Factor, Student Bodies, The It Factor, and Oz.
