Narrator: From her beginnings on a Navy drawing board, through the months of secret field experiments out on the Western desert, then through the desperate search for new metals with the properties she needed, she was designed to be the nation's greatest weapon of the seas - the atom-powered submarine. Her engines were to be a miracle of speed and power, her sides strong enough to withstand any blow, her armament and fire power of greater force than the worst enemy she might encounter. The ...

The Abyssal Octopus
15 July 2015 | by (Rio de Janeiro, Brazil) – See all my reviews

The state-of-art atomic submarine under the command of Commander Pete Mathews (Kenneth Tobey) is hold back by something weird in the sea. Pete reports to the Admiral and contacts the prominent scientists Prof. Lesley Joyce (Faith Domergue) and Dr. John Carter (Donald Curtis) to investigate. They conclude that the submarine was attacked by a giant radioactive octopus developed from bombing tests in the Pacific Ocean that would threaten the oceans. The Navy Command does not accept the explanation, but when a ship is sunk by the octopus, they realize the menace. Cmdr. Mathews teams-up with Carter and Joyce and has a love affair with her. But soon the monster attacks San Francisco and the trio is the only chance to stop the creature.

"It Came from Beneath the Sea" is a weak sci-fi about an abyssal octopus, fruit of bomb tests in the ocean. I am a big fan of Sci-Fi's from the 50 's, but this one is too dated, military and lame. The story takes place after WWII and during the Cold War in a period when the military people were in the summit of their careers; but there are many others good movies from this period. The greatest problem is the lack of action, with the romance without any chemistry between Pete and Joyce with John Carter with them all the time in a total waste of time. The period of research is also too long. The stop-motion effects are OK for a 1955 film. The good point is Prof. Lesley Joyce, a woman ahead of time with her independence and not fainting or screaming like most of the heroins from the 50's and 60's movies. My vote is four.

Title (Brazil): "O Monstro do Mar Revolto" ("The Monster from the Choppy Sea")
