* AwesomeMusic
* 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 season they'd gone quite loopy and neck-deep into fantasy elements. Whether that's [[BrokenBase a good or bad thing]] is up for debate, but it's hard to believe that the show moved from "City Beneath the Sea" to something like "The Deadly Dolls" (the latter is exactly what it sounds like: a story about cursed puppets that would seem more at home in ''Series/TheTwilightZone'' than in what began as "serious" SciFi).
* SpecialEffectsFailure: The giant squid in the film. Also, the shark is clearly a plastic toy.
