It Came From Beneath the Sea is enjoyable on so many levels. First and foremost, it is an example of the early stop-motion special effects of Ray Harryhausen, with a giant octopus (which actually has only six legs due to budget constraints) attacking the Golden Gate Bridge. For a B film ’50s sci-fi film, the production values are actually pretty good. There is some unintentional comedy, such as scene in which three new characters are introduced wearing ant-radiation suits which completely obscure their bodies, most of their faces, and muffle their voices. And finally, this film depicts one of the most bizarre love triangles ever committed to film. The talented and lovely marine biologist Lesley Joyce (Faith Domergue) is engaged to a colleague (Donald Curtis) at the opening of the film, but atomic submarine commander Pete Mathews (Kenneth Tobey) shows up to enlist their help to research a mysterious creature that has attacked a submarine. The commander openly flirts with the doctor, right beneath the nose of her fiancé, who is at first slightly concerned, but latter chuckles at what is going on.
