The Ultimate Vampire Resource and Directory

Westworld is a 1973 science fiction / thriller film written and directed by Michael Crichton. It stars Yul Brynner, Richard Benjamin, and James Brolin. It was followed by a sequel, Futureworld, and a short-lived television series, Beyond Westworld.

The Gunslinger's appearance is based on Chris, Brynner's character from The Magnificent Seven. Both characters wear the same costume.

In the scene when Richard Benjamin's character splashes "The Gunslinger" (Yul Brynner) in the face with acid, Brynner's face was covered with an oil-based makeup mixed with ground Alka-Seltzer. A splash of water then produced the fizzing effect.


Westworld was the first major feature film to use 2D computer generated images (CGI) during scenes showing the point of view of the robotic gunslinger. The first use of 3D CGI in a feature film was Westworld's sequel, Futureworld, in 1976.

Information International, Inc., better known as Triple-I, created the digitized shots of The Gunslinger's point of view for the movie. According to Turner Classic Movies, some of the shots took eight hours to render completely, and many tests were made to get the right look.
