Why this pick
Like Tentacles, it makes an ordinary coastal community vulnerable to a large sea-borne threat, with brisk B-movie pacing, anxious officials, and a satisfying creature-feature escalation.
Why this pick
A foundational giant-monster thriller whose waterfront destruction, scientific problem-solving, and grave atomic-age mood closely suit Tentacles’ coastal disaster energy.
Why this pick
For Tentacles’ pleasure in military-scientific teams confronting an outsized predator, this Arctic-to-city creature feature offers earnest investigation and clean, suspenseful escalation.
Why this pick
Another seventies nature-runs-amok thriller, it shares Tentacles’ pulpy seriousness, practical oversized-animal spectacle, and escalating attacks on an isolated community.
Why this pick
Released the same year, it turns the ocean into an arena of sustained predator-versus-human tension, with a grim, weather-beaten mood that complements Tentacles’ aquatic menace.

01 / THE STORY
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.
