Gamera vs. Zigra (1971)

In an unexpected celestial catastrophe, a lunar base succumbs to destruction by an alien spaceship, its head bizarrely adorned with a cluster of gumballs. The tranquillity of Earth's Sea World is then shattered as dolphins start perishing in an inexplicable epidemic. Abruptly, the menacing Zigra emerges, kidnapping two men and a pair of children, one with an obsessive fondness for Coca-Cola. Unleashing a reign of terror, Zigra commences a series of devastating earthquakes, threatening to destabilize the world. Meanwhile, the two young hostages, despite their tender age, ingeniously outsmart Zigra, helping their incapacitated fathers escape its clutches. Enter the Zigra Woman, a terrifying entity with the hypnotic ability to induce comas with her gaze. She ensues in a relentless pursuit of the group across Sea World, a chase which unfolds like an extended, enthralling spectacle. Eventually, the film's eponymous hero, Gamera, crashes onto the scene. The giant turtle engages in a monumental clash with Zigra, who morphs into an enormous swordfish. The movie is a rollercoaster of suspense, action, and unexpected twists, promising a thrilling ride from start to finish.
