American juvenile leading man. A native of Texas, Martin entered the theatre in 1946 and within three years was tapped to play one of the young toughs in Knock on Any Door (1949). After minor roles in several minor films, he was given a larger role in The Thing from Another World (1951) by producer Howard Hawks. Hawks followed this with one of the two lead roles in his great Western The Big Sky (1952). Despite this and a few other prominent parts in big pictures, Martin's appearances became more and more infrequent and less and less stellar. He did, however, become a familiar face on television into the 1970s. He was married to singer Peggy Lee in the late 50s.
