** Dick Van Patten (aka [[Series/EightIsEnough Tom Bradford]]) is one of the theme park guests.

* RecycledINSPACE: 15 years later, Michael Crichton would write his most famous story, ''Literature/JurassicPark'', which is also about an amusement park where the attractions go crazy and attack the guests (only this time they were cloned dinosaurs, not robots).
* TechnologyMarchesOn: The sheer number of reel-to-reel computers running the resort are one obvious case. Another is that the spreading malfunction of the Delos robots is described in terms of an infection, which the heads of Delos laugh off -- keep in mind that this came out two years after what is commonly described as the first computer virus, and almost a decade before the first time one infected anything outside of the lab where it was created.
