Tentacles

It slept until man disturbed it, then it wove to the fury no man could control. Tentacles, the giant octopus, with eight writhing awe, deadlier than the claws of a tiger, eight tons of bone-crunching terror that tears apart a quiet seaside community.

Tentacles, starring John Houston, Shelley Winters, Beau Hopkins, Claude Akins, and Henry Fondell. Tentacles, a fight to the death between the mighty jaws of a killer whale and the awesome power of a giant octopus. No sea monster of mytho legend is half so deadly as one that actually exists, tend to put it in the most perfect suspenseful of history.
