When the Earth is threatened by a burning Van Allen Radiation Belt, US Navy Admiral Harriman Nelson plans to shoot a nuclear missile at the Belt using his experimental atomic submarine, the Seaview. (IMDb)
An undersea sci-fi adventure that loses its credibility as soon as a global disaster comes out of left field in the form of a terrible looking sky on fire. The world-saving submarine mission established henceforth (featuring a tiresome repeated external sub shot) is just as outrageous and poorly written, with the crew and captain melodrama within the visually superior indoor sets offering only slight consolation. It’s a film that’s never substantial, and only occasionally entertaining.
