Futureworld (1976)

Upon uncovering the dirty secret of futuristic theme-park Futureworld, an ex-employee is killed after he tips off two other reporters who decide to do an undercover investigation. In this sequel to "Westworld," two reporters are invited to Futureworld, a 'Disneyesque' resort for adults, to see what changes have been made since the early model robots went haywire and killed some guests. Once there, they discover a grandiose scheme to replace the leaders of the world's most powerful nations with robot clones.
