Dolores put a version of her own mind inside a copy of Charlotte Hale's (Tessa Thompson) body for the purposes of smuggling several "pearls" (containers for host minds) out of the park. However, in season 3 it was revealed that rather than smuggling out any other hosts, Dolores had simply made more copies of her own mind for the purposes of replacing key humans in the outside world.
Released in 1976, Futureworld was a hastily-made sequel intended to cash in on the success of the original movie. Unfortunately, Westworld's writer-director Michael Crichton wasn't interested in making a sequel, and Futureworld was instead directed by Richard T. Heffron. The film is set two years after the original, with Delos having reopened its robot-filled theme parks. Westworld has been left in ruins, and replaced by two new parks: Spaworld (where older guests can live out the fantasy of being young again) and Futureworld (which simulates life in space).
Futureworld is a pretty weird sequel. The only returning cast member from the original movie is Yul Brynner as the Gunslinger, and he only appears for a couple of minutes as the rescuing hero in an erotic dream that TV reporter Tracy Ballard (Blythe Danner) has. The plot, however, is interesting when compared to that of Westworld season 3. While putting together a story on the supposedly new and improved Delos parks, Tracy and her fellow reporter Chuck (Peter Fonda) discover that Delos is now being run by robots, who are inviting world leaders and other powerful figures to the parks so that they can be cloned and replaced.
These clones are human in almost every respect, but have been brainwashed to destroy their originals and carry out Delos orders. The parallels to Futureworld actually began in Westworld season 2, when it was revealed that Delos had been closely monitoring guests at the park and their behavior with the goal of ultimately making copies of their minds, like they did with James Delos. In Futureworld, the targeted visitors are under constant surveillance and their appearance and mannerisms are recorded by a team of robot scientists for the purposes of creating perfect clones of them.
The similarities between Futureworld and Caleb puts it, a world with a "coat of paint on it - but inside, it's rotting to pieces."
Unfortunately Futureworld doesn't delve as deeply into the idea of computers controlling free will as Westworld season 3 does. As in the original movie, the robots are portrayed more or less as straightforward villains, and the humans triumph over them in the end. In that sense, Westworld has an opportunity in season 3 to capitalize on an interesting idea that didn't get the attention it deserved in the 1976 movie. With two episodes left in season 3, it remains to be seen whether Dolores' plan to conquer the world with the strategic replacement of humans will work better than the last time it was attempted.
