La fiera del mar

A nuclear sub is taking its' shakedown cruise when the Captain puts on Swing music on the stereo. The monster disapproves of his music choice and pins down the sub. The sub eventually gets free, but there is unidentifiable matter stuck to it. Eventually scientist Faith Domergue figures out it belongs to a giant octopus.

Director Robert Gordon does a good job of not letting the film get bogged down in talk. Domergue and the Navy argue about whether sea monsters actually exist. The film is worth watching for the stop-motion animation Harryhausen did on a limited budget. The monster is marvelously realistic looking as it wreaks havoc upon the countryside.
