Handsome laconic American leading actor of the 50s and 60s most often cast as servicemen or brawny outdoor types Never a serious contender for movie stardom he was better served on the small screen as a guest actor in westerns and police dramas A native New Yorker Sean had left school at 14 and taken on a host of shortterm jobs on ranches construction gangs and sponge boats before landing himself a position at the ABC film vaults in Hollywood He was subsequently signed by Warner Brothers and made his film debut in a bit role in 1958 He went on to study drama at the Actors Studio in New York at one time supplementing his income as a Macy Department Store Santa Claus Sean appeared twice on Broadway in the early 60s and played Lancelot in a touring theatre production of Camelot Since he had a good baritone voice he was tipped to play the part in the motion picture as well but ultimately lost out to Franco Nero who ironically had to be dubbed He did eventually score a leading movie role of note as a naval ensign opposite Jean Seberg in the psychological thriller Moment to Moment 1966 However his performance seemed somewhat muted and the director Mervyn LeRoy later expressed misgivings in not having cast an actor of Paul Newmans caliber instead Sean briefly costarred with John Mills in a 1967 series as an impulsive hotshot lawyer slash gunslinger apprenticed to a pacifist greenhorn British attorney involved in legal proceedings in 19th century Arizona Despite its rather offbeat premise and benefiting from being shot in color frequently on location Dundee and the Culhane 1967 flopped and was canned after just 13 episodes Sean was essentially relegated to the fringes of screen acting thereafter and retired in the early 80s to go into the swimming pool construction business
