Written and directed by science fiction author Michael Crichton, Westworld debuts in theaters, mashing up familiar western tropes with a tale of cyborgs gone mad. Richard Benjamin (Quark), James Brolin, and Yul Brynner guest star; Majel Barrett (Star Trek) and Dick Van Patten play cameo roles. A hit for MGM, Westworld will spawn many attempts to follow up on its success, from the 1976 movie Futureworld to numerous TV revivals well into the 21st century.
