Actor Marc Singer made his movie bow in Go Tell the Spartans (1978), after a few guest shots on such TVers as Hawaii 5-0. In films, Singer is most closely associated with the role of Dar, the bare-chested sword-and-sorcery protagonist of the Beastmaster films. On TV, he played aspiring pugilist Johnny Captor in the five-week miniseries The Contender (1980), extraterrestrial-bashing hero Mike Donovan in V (1984-85) and Matt Cantrell in the 1986 episodes of Dallas.
