I think it would have been at least plausible, in a way." Despite Carbone's feelings about Corman's filmmaking, he stated that the film was "very funny" and he "had a lot of fun doing it". When the cast and crew had difficulty getting out of the country, the cinematographer hid the film from Corman until the cast and crew got paid for the production. Actress Betsy Jones-Moreland stated of the production that "the only problem with that movie is that it started out to be a takeoff on everything Roger had ever done before. It was to be a comedy, a laugh a minute. Then all of a sudden, somewhere in the middle of it, that got lost and it got to be serious." Moreland continued to state that she "just assumed that nobody would ever see it.

The score was used in a total of seven films, including The Wasp Woman and The Little Shop of Horrors. Release Creature from the Haunted Sea was not released until 1961.

The film's poster asks "What was the unspeakable secret of the sea of lost ships?" and requests that audiences "do not give away the answer to the secret." Many audiences found the advertising to be misleading, which hurt the film's box office. In March 1963, Corman reassembled the cast in Santa Monica to appear in new scenes directed by Monte Hellman for television airings of the film, expanding the length to 74 minutes. A title song, sung by Betsy Jones-Moreland, was added by Hellman on the assumption that a film called Creature from the Haunted Sea should have a title
