Delos, but, just as they reach the exit, Ballard's badly injured clone stumbles towards him and Schneider realizes too late that he has been fooled. On the jetway, Browning tells Ballard that his editor is running the exposé on Delos, that the whole world will know what they are up to, and that kissing her was his idea to figure out whether or not she was a duplicate.

Michael Crichton did not wish to be involved in a sequel, so they approached the original producer Paul Lazarus III. He developed an idea set in a successor world to Westworld where robots are cloning world leaders. He found a writer and developed a script; MGM decided to only make one science fiction film that year, Logan's Run. Futureworld was put into turnaround. Lazarus had trouble finding production and distribution for the film elsewhere, because other studios were confused and wary after MGM passed on it, especially since the original film had been a financial success for MGM. Lazarus was approached by former MGM president James T. Aubrey who said he could get the film made. He arranged financing from Samuel Z. Arkoff's American International Pictures. Futureworld was the first major feature film to use 3D computer-generated imagery (CGI). CGI was used for an animated hand and face. The animated hand was a digitized version of Edwin Catmull's left hand, taken from his 1972 experimental short subject A Computer Animated Hand. The animated face was taken from Fred Parke's 1974 experimental short subject Faces & Body Parts. The film also used the 2D technique of digital compositing to materialize characters over the background. Futureworld utilized the "Logan apartment set" from Logan's Run and redressed it to be the Futureworld bar. Filming Much of the film was shot in the greater Houston area, including Intercontinental Airport, Jones Hall, and the Johnson Space Center. The
