Rodolfo Acosta

With one look at Rodolfo Acosta and his pointed, sly features, it makes complete sense that the Mexican character actor made his mark playing villains, primarily in Westerns of the 1950s and '60s.

After a small role in John Ford's 1947 drama "The Fugitive," Acosta found himself quite at home in Hollywood, landing antagonist roles in Westerns starring heavy-hitters such as John Wayne ("The Sons of Katie Elder") and Marlon Brando ("One-Eyed Jacks").

While he rarely secured recurring characters on television, he often popped up in guest roles on many high-profile series of the time, including "Mission: Impossible," "The Outcasts," and "Bonanza."
