To enjoy any movie, one must suspend disbelief. The problem with watching "Voyage to the Bottom of the Sea" is that, from beginning to end, the absurdities keep coming so thick and fast that suspension of disbelief would require the assistance of a powerful hallucinogen. If there is any other main-stream motion picture ever made that is packed with more pseudo-scientific babble and less understanding of science and technology, I have not seen it. The best moments of the movie are as silly as any Japanese monster movie, providing unintended laughs; the worst parts are simply abysmal. It is patently obvious that no one involved with the production of this movie had the slightest knowledge of either science or submarines or, if they did, they did not use it. From the absurd plot about the Van Allen belt to the even more absurd solution to the problem, and from a diving alarm that sounds like a runaway semi, to impossible diving depths, there is no believability anywhere in this movie. The Seaview itself, however, should be the envy of every naval architect. Not only are its compartments larger and have higher overheads (ceilings to landlubbers) than any compartment on any surface warship, the Seaview actually is larger on the inside than the outside! And while I realize the movie was made in 1961, whose decision was it to put tail fins on a submarine, for crying out loud? The most important thing this movie accomplished was to teach Barbara Eden to play comic fantasy with a straight face, thereby preparing her for her role as Jeannie in a TV sitcom that was far more realistic than this movie.
