He was going to make the film independently . The rights eventually went to Disney . </P> <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> <P> With a total (and greatly over-run) production cost of $9 million, the film was the most expensive in Hollywood to that date and presented a serious financial risk to the studio should it flop . </P>
