Gamera vs. Zigra (ガメラ対深海怪獣ジグラ, Gamera tai Shinkai Kaijū Jigura, lit. 'Gamera vs. Deep-Sea Monster Zigra') is a 1971 Japanese kaiju film directed by Noriaki Yuasa, written by Niisan Takahashi, and produced by Yoshihiko Manabe and Hidemasa Nagata. It is the seventh entry in the Gamera film series, after Gamera vs. Jiger, which was released the previous year. Gamera vs. Zigra stars Eiko Yanami, Reiko Kasahara, Mikiko Tsubouchi, and Kōji Fujiyama, and features the fictional giant monsters Gamera and Zigra.
Shortly after Gamera vs. Zigra was completed, the film's production studio, Daiei Film, went bankrupt. As a result, the film was distributed by Dainichi Eihai, receiving a theatrical release in Japan on July 17, 1971. The film was not released theatrically in the United States, instead being released directly to American television by King Features Entertainment in 1987.
Plot
In 1985, without warning, an alien spaceship attacks a Japanese Moon base. Back on Earth, young Kenichi (Kenny in the English dubbed version) Ishikawa, his father Dr. Yosuke (Henry in the English dubbed version) Ishikawa, his friend Helen Wallace and her father, Dr. Tom Wallace, witness the spaceship descending into the ocean. They go to investigate, but are soon captured by a teleportation beam that brings them aboard the spaceship. Inside the spaceship, a human-looking woman appears to them and reveals that she is of an alien race called the Zigrans. By way of demonstrating Zigran technological prowess, she creates a gigantic earthquake that wreaks havoc in Japan. She had previously caused two other earthquakes, one in Peru and the other in Arabia (in the English dubbed version, it mentions instead the Indian Ocean). She then tells her prisoners of the planet Zigra's history and its great scientific advances which, unfortunately, have resulted in its destruction; but in searching for a new home, Zigra has found Earth.
