Voyage to the Bottom of the Sea is a 1960s American Science Fiction television series based on the 1961 film of the same name. Both were created by Irwin Allen, which enabled the movie's sets, costumes, props, special effects models, and sometimes footage, to be used in the production of the television series. Voyage to the Bottom of the Sea was the first of Irwin Allen's four science fiction television series. The show's main theme was underwater adventure.
