The son of Broadway singer/actor Harry Stockwell, Guy Stockwell made his stage debut at age 5 in The Innocent Voyage. Also appearing in this 1943 Theatre Guild production was Guy's younger brother Dean Stockwell. Dean went on to fame as a child actor, specializing in sensitive roles; conversely, Guy did not truly achieve prominence until adulthood, playing rugged, outdoorsy types.
More active on the stage than on screen, Guy nonetheless chalked up plenty of on-camera credits, including regular roles on such TV series as Adventures in Paradise (1961), The Richard Boone Show (1963), and the daytime drama Return to Peyton Place (1972; as Dr. Michael Rossi). Guy Stockwell's best big-screen assignment was the title role in the 1966 remake of Beau Geste. ~ Hal Erickson, All Movie Guide.
