Westworld

A lawyer and businessman (Richard Benjamin and James Brolin) take a dream holiday to the newly opened technological paradise Westworld, a resort offering its visitors all the thrills, but none of the dangers, of the old Wild West, which is recreated by supposedly harmless robots. However, when one of the computerized gunslingers (Yul Brynner) malfunctions, the two city slickers find themselves in a battle for their lives. Directorial debut of Michael Crichton.
