Despite a number of harsh criticisms, Voyage to the Bottom of the Sea is a thoughtful and entertaining sci-fi film with an intelligent premise. When the submarine Seaview discovers a strange, burning sky over the Arctic with temperatures unusually warm, its crew learns that the Van Allen Radiation Belt surrounding the earth has somehow caught fire, threatening to roast the earth unless something can be done to stop it. With temperatures around 170 degrees and communications with Washington cut off, Admiral Nelson (played nicely by Walter Pidgeon) orders the Seaview to the North Pole, with the intention of firing a nuclear missile as a solution to the ensuing catastrophe. Unfortunately, Captain Crane (Robert Sterling) and most of the crew are at odds with the Admiral's intentions. Attempted mutiny follows, while enemy subs, giant sea creatures, and sabouteurs try to foil the mission. Peter Lorre swims in a shark tank, Barbara Eden dances to Frankie Avalon's trumpet, and Michael Ansara plays the religious fanatic. While nowhere in the realm of the sci-fi classics, this is, nonetheless, a colorful and entertaining film with good acting (from most of the cast) and good special effects - a worthy and necessary inclusion in any serious sci-fi collection.
