<P> 20,000 Leagues Under the Sea was filmed at various locations in The Bahamas and Jamaica , with the cave scenes filmed beneath what is now the Xtabi Resort on the cliffs of Negril . Filming began in spring of 1954 . Some of the location filming sequences were so complex that they required a technical crew of more than 400 people . The film presented many other challenges , as well . The famous giant squid attack sequence had to be entirely re-shot , as it was originally filmed as taking place at dusk and in a calm sea . The sequence was filmed again , this time taking place at night and during a huge gale , both to increase the drama and to better hide the cables and other mechanical workings of the animatronic squid . </P>
