* ArtisticLicenseScience: So very, very much of it in the film.
* ColbertBump: The show would probably be a lot more obscure now without ''Series/MysteryScienceTheater3000'' having featured a RunningGag of Gypsy's obsession with Richard Basehart.
* SeasonalRot: The television series began with largely the same tone as [[Film/VoyageToTheBottomOfTheSea the 1961 film]], but by the fourth series they'd gone snooker loopy. It's hard to believe that the show moved from "City Beneath the Sea" to something like "The Deadly Dolls". The latter is exactly as stupid as it sounds.
* SpecialEffectsFailure: The giant squid in the film. Also, the shark is clearly a plastic toy.
