Westworld is a 1973 American science-fiction Western thriller film written and directed by Michael Crichton. Its plot concerns amusement park androids that malfunction and begin killing visitors. It stars Yul Brynner as an android in a futuristic Western-themed amusement park, and Richard Benjamin and James Brolin as two of the guests.
Westworld is a place where paying guests can pretend to be gunslingers in an artificial Wild West populated by androids. After paying a sizeable entrance fee, Blane and Martin are determined to unwind by hitting the saloons and shooting off their guns. But when the system goes haywire and Blane is killed in a duel with a robotic gunslinger, Martin’s escapist fantasy suddenly takes on a grim reality as he tries to survive the vacation of a lifetime.
Yul Brynner is the star of the show in this perfectly decadent example of revelatory seventies cinema.
