Godzilla vs. Mechagodzilla (1974)

Synopsis
This time, the overgrown-lizard hero is confronted by a mechanical doppelganger, courtesy of an army of extraterrestrial apes. Unable to best his metallic twin in combat, Godzilla seeks out the aid of Okinawan monster god King Seeser. The film is peppered with moments of humor; so much happens in the final reel that one is disappointed not to see the kitchen sink. After the TV popularity of The Six Million Dollar Man and The Bionic Woman, Godzilla vs. Mechagodzilla was rechristened Godzilla vs. the Bionic Monster. ~ Hal Erickson, All Movie Guide
