Tentacles (1977) (Patreon)

When  numerous people go missing in a seaside resort town, reporter Ned  Turner (John Huston) helps to uncover the reason -- a gigantic rampaging  octopus. As the eight-legged monster continues to terrorize the coast,  marine biologist Will Gleason (Bo Hopkins) attempts to devise a way to  stop the octopus before more tourists fall  victim to the creature. Meanwhile, it appears that a corporation headed  by Mr. Whitehead (Henry Fonda) may be connected to the cephalopod's  violent behavior.
