For anyone who ever thought Jaws could use more tentacles—and a touch of Italian flair.

Hollywood Heavyweights

John Huston, Shelley Winters, and Henry Fonda bring serious star power to this Italian-American creature romp.

Killer Whale Showdown

Few monster movie finales deliver quite like a pair of killer whales taking on a giant octopus.

Psychotronic Surrealism

With mutated animals, questionable science, and a bribe-fueled cover-up, this film scores high on psychotronic weirdness.

About This Film

Solana Beach, a seaside tourist resort, has come under attack by a giant octopus, which captures and devours human swimmers and boaters, picking the skeletons clean of flesh and bone marrow. Marine expert Will Gleason (Hopkins) and crusading newspaper reporter Ned Turner (Huston) suspect the construction of an underwater tunnel by the Trojan company, owned by Mr. Whitehead (Fonda). Trojan has been using radio signals that have been "above regulated levels", somehow maddening the octopus and causing it to attack human beings. In the end, the octopus is killed by Gleason's pair of killer whales. 

Several people disappear from and at the sea. Their bodies are found gnawed to the skeleton, even the marrow is missing. The scientists have no idea which animal could do such things. Dr. Turner begins to suspect that the company which builds a tunnel beneath the bay might have poisoned the environment and caused an octopus to mutate to giant dimensions.
