Terror of Mechagodzilla

Terror of Mechagodzilla (メカゴジラの逆襲, Mekagojira no Gyakushū, lit. 'Mechagodzilla's Counterattack') is a 1975 Japanese kaiju film directed by Ishirō Honda, written by Yukiko Takayama, and produced by Tomoyuki Tanaka and Henry G. Saperstein, with special effects by Teruyoshi Nakano. Distributed by Toho and produced under their effects subsidiary Toho–Eizo, it is the 15th film in the Godzilla franchise, serving as a direct sequel to the 1974 film Godzilla vs. Mechagodzilla and the final entry of the franchise's Shōwa era and the last to be directed by series co-creator Ishirō Honda before his death in 1993. The franchise would be rebooted nine years later with The Return of Godzilla, beginning the franchise's Heisei era.

Terror of Mechagodzilla stars Katsuhiko Sasaki, Tomoko Ai, Akihiko Hirata, and Gorō Mutsumi, and features Toru Kawai, Kazunari Mori, and Tatsumi Nikamoto as the fictional monster characters Godzilla, Mechagodzilla 2, and Titanosaurus, respectively. The film was released theatrically in Japan on March 15, 1975, to mostly positive reviews. It was released in the UK in June 1976 under the title Monsters From an Unknown Planet. It received a limited release in the United States in 1978 by Bob Conn Enterprises under the title The Terror of Godzilla. The film remains the least financially successful entry in the Godzilla franchise to this day.
