1950s sci-fi monster movie about a giant octopus attacking ships and submarines. The Navy doesn't like it one bit. Slow-going with the monster octopus not fully showing up until three-quarters into the picture. Far too much focus in the first half on the nauseating romantic drama involving Kenneth Tobey's sub commander and scientists Faith Domergue and Donald Curtis. There is some fun to be had with the clichéd characters and some of their corny lines ("When you're driving that atomic submarine of yours, do you have time for romance?"). All of the octopus scenes are fun and the last quarter of the movie is the most interesting, due to the stop-motion effects from the legendary Ray Harryhausen. I normally love movies like this and would rate it higher, but it's just so talky and the romance makes me want to puke.
