American leading man Richard Derr made his first film appearances as a 20th Century-Fox contractee in 1941 and 1942. Physically indistinguishable from most others of his ilk, Derr nonetheless was an above-average actor, as he occasionally proved in such films as When Worlds Collide (1951). In 1957, Derr was cast as Lamont Cranston in the New Orleans-filmed pilot episode for the TV version of radio's The Shadow; the series didn't sell, but the pilot was released theatrically as Invisible Avenger. Richard Derr spent the 1970s and 1980s as a utility character man in films like The Drowning Pool (1975) and American Gigolo (1980).
