Tentacles (1977)

Tentacles (Italian title: Tentacoli) is a 1977 Italian-American horror film directed by Ovidio G. Assonitis and starring John Huston, Shelley Winters, Bo Hopkins and Henry Fonda. When numerous people go missing in a seaside resort town, a reporter discovers a rampaging giant octopus is terrorizing the coast. While a marine biologist attempts to stop the octopus before more tourists fall victim to the creature, it appears that a corporation may be connected to the cephalopod's violent behavior. Although the film was intended to cash in on the success of Jaws, Tentacles also bears numerous resemblances to the 1955 science fiction giant monster horror film It Came from Beneath the Sea.

Plot

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.
