Good Grade B '50s sci-fi flick. An atomic size octopus from the deepest realms of the Pacific threatens the world. Seeking adequate levels of food supply, not excluding humans, the creature attacks San Francisco. The real star of this movie is the razzle-dazzle special effects of Ray Harryhausen. The quality of the stop-motion animation exceeds the constraints of the B&W photography and the modest budget. The first part of the film tells of the mysterious ship sinking and other unexplained marine mayhem caused by the great sea beast. Navy Captain Pete Mathews (Kenneth Tobey) and two expert marine-biologists, John Carter (Donald Curtis) and Lesley Joyce (Faith Domergue), work around the clock tracking down clues to identify the source of the mysterious events at sea. The simple plot moves right along and doesn't waste time. As seems obligatory in many '50s sci-fi flicks, the heroes endure the "I'm telling you, there's a monster!" phase followed by the "Yeah, right!" response from the authorities. Happily, that particular cliche is kept to a minimum. Things really start to go snap, crackle, and pop as the monstrous octopus tries to pull itself up on the Golden Gate Bridge. And check out the giant eye that opens as the submarine approaches the submerged creature in the San Francisco harbor. This is solid Saturday afternoon at the movies fun for 12 year-olds of all ages. They really don't make them like this anymore.
