You can see the roots both in the plot and the special effects in Michael Crichton's Westworld that can later be found in the incredibly popular Jurassic Park series.
Like Jurassic Park the protagonists of Westworld are a pair of wealthy American yuppies who are going to a futuristic vacation resort. The place is called Delos and like Disneyland with its separate theme parks of Fantasyland, Adventureland, Frontierland, and the World of Tomorrow, Delos has three different resort type places to visit, Romanworld, Medievalworld and Westworld.
Our two intrepids have chosen the Westworld experience. They get to mix and mingle in an old west frontier town, or at least a Hollywood type version of same and get the feel of western life. Included are gunfights and bar brawls such as you see in any good Hollywood western. This is what Richard Benjamin and James Brolin have chosen for themselves.
For reasons unexplained in the story, the whole thing breaks down in all three theme worlds and in the case of Westworld, a very nasty gunslinger robot has shaken loose from his programming and is on the hunt for human targets. Will man with all of his weaknesses defeat an apparently indestructible machine?
You can also see some of the themes in the later Terminator films that Arnold Schwarzneggar popularized. Here the relentless hunter is played by Yul Brynner in the familiar black western garb that he made popular in The Magnificent Seven.
The VHS copy of Westworld advertises itself as the very first use of computer graphics. If that's the case this is one unique experience for that reason alone and should not be missed.
