Westworld is a 1973 science fiction western-thriller film written and directed by novelist Michael Crichton and produced by Paul Lazarus III. The movie is about amusement park robots that become evil after a power surge, and they start to take over. It served as the beginning of a franchise followed by a sequel film called Futureworld and a short-lived television series called Beyond Westworld. The film was very successful.
In August 2013, HBO announced plans for a TV adaptation based on the original film.
In the near future, there is a high-tech, highly realistic adult amusement park called Delos that features three themed "worlds" — Westworld (the American 1880's West), Medieval World (medieval Europe), and Roman World (pre-Christian Rome). The resort's three "worlds" are populated with lifelike androids that are practically indistinguishable from human beings, each programmed in character for their assigned historical environment. People pay to indulge in adventures in each of the worlds where they interact with the android population. Guests are encouraged to do anything they feel like, including killing any of the androids or having sexual intercourse with the gynoids (feminine robots). The film begins with a TV commercial where a Delos employee is interviewing people at the airport who just returned from Delos and are pleased with their stay, and the employee announcing "Boy, have we got a vacation for you!"
Peter Martin is a first time visitor. He and a friend, John Blane, a return visitor, are taken by hovercraft to Delos' resort in the middle of the desert. The hovercraft disembarks at an underground processing facility. Guests are segregated by color-coding, through yellow (for Roman World), red (for Medieval World) or blue (for Westworld). The guests are attired in clothing appropriate for their chosen period and sent down a tunnel which surfaces in the respective "world". Much of the film is shown with Peter and John in Westworld, although it intersperses with some of the other parts of Delos.
In Westworld, Peter sees that Delos is strict about historical accuracy, right down to the artifacts having been made in the actual years. John says they can use their guns to kill androids, but Peter expresses concern about who is who, considering the androids look identical to guests (with exception of small indentations on the hands). John challenges Peter to shoot him, but when Peter does so, his pistol fails to discharge. John explains that the pistols have heat-sensitive trackers. Androids have a low body temperature, but the pistols do not fire if they detect a certain heat range, in which case they will not activate near the high body temperatures humans are known for. Peter remarks that Delos thought of everything.
The technicians running Delos notice problems are beginning to spread among the androids, but things go wrong in attempts to shut down power and the androids. Running on reserve power, the robots run amok and Delos becomes a death trap for its guests.
