Monster Zero

Monster Zero is a 1965 film. Part of the Godzilla series, it was produced by Toho studios. Directed by Ishiro Honda and with special effects by Eiji Tsubaraya, its original title was Kaiji Dia Senso ("Invasion of Astro-Monster").

In this particular movie, extraterrestrials ask to borrow two earth-bound monsters (Godzilla and Rodan) in order to combat their own terror (King Ghidora, or "Monster Zero"). Or so it seems at first. This film is very similar to its predicessor Ghidorah the Three Headed Monster.
