Doug McClure began his acting career in the late 1950's, appearing both in films and on television. His friendly, easy going manner and good looks landed him a lot of television work. In 1960, he was hired for the CBS series Checkmate
, which lasted only two years. It was the roles he played on several Western series, however, that led to a starring role in the 1962-1971 NBC series The Virginian
, where Doug played Trampas, the role for which he was most known.
