It is "Westworld" (translated in Spain as " Metal souls "), a 1973 science fiction film written and directed by Michael Crichton (Jurassic Park, The Lost World), which places us at an indeterminate moment in the future in the one in which the protagonist is a high-tech amusement park, "Delos", which shows its visitors the ability to interact with humanoid robots integrated in different settings of history such as Ancient Rome or the Middle Ages. The ability to interact with visitors is such that they even responded to propositions of a sexual nature.
The film, starring Yul Brynner, Richard Benjamin and James Brolin, used the 2D computer generated images during the scenes in which the action was shown from the point of view of one of the robots: the gunman . These 2D images were developed by Information International, Inc.
As a curiosity, the first film to use computer-generated images but, this time, in three dimensions, was the sequel to Westworld, called Futureworld , which was released in 1976.
