From Wikipedia, the free encyclopedia Frank Clarke (29 December 1898 – 12 June 1948) was a Hollywood stunt pilot, actor, and military officer. His most prominent role was as Lieutenant von Bruen (and double for von Richthofen in combat scenes) in the 1930 production Hell's Angels, but he flew for the camera and performed stunts in more than a dozen films in the 1930s and 1940s. Clarke was killed in an aircraft crash near Isabella, California, in 1948.
