Did You Know?


Several subs appear in stock footage. The jet-propelled torpedo gets loaded onto a real sub that appears to have a fake conning tower, probably built over the real conning tower to make this sub visually match the sub that appears later. It's hard to read the sub's number in the torpedo-load scene, but it appears to be 334 - - USS Cabezon. Cabezon arrived in California 1953 to join the reserve fleet and might have been undergoing inactivation when the film crews set up. See more »


In the final scene, Commander Mathews' uniform does not have the star above the three stripes on his sleeve. This designation is worn by unrestricted line officers (those who command naval warships). See more »

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 ...

I Left My Tentacle in San Francisco
9 September 2000 | by (NC) – See all my reviews

Ray Harryhausen wonderfully creates a giant octopus ravaging the Pacific Coast and then rooting itself in San Francisco Bay. The octopus is quite stunning and a marvel of stop-motion animation. Viewers are treated to it actually climbing on the Golden Gate Bridge(a model of course), squeezing a submarine, literally bringing a ship down to the depths, and throwing tentacles all over pedestrians in the San Francisco harbour. My only regret is that this is all too infrequent and most of it arriving at the end of the film. The rest of the story centers around Kenneth Tobey, Faith Domerge and Donald Curtis trying to discover what it is that held Tobey's submarine. There is also a weird love triangle among the three as well which enhances the story I believe. All in all this is a fine piece of classic science fiction entertainment.
