Invasion of Astro-Monster
Appearance
Invasion of Astro-Monster (also known as Monster Zero and Godzilla vs Monster Zero) is a film released in 1965. It was produced by Toho studios as part of the Godzilla series and directed by Ishiro Honda with special effects by Eiji Tsuburaya. The original Japanese title was Kaiju Dai Senso (Monsters' Large War).
In the plot, extraterrestrials from Planet X ask to borrow two earth-bound monsters (Godzilla and Rodan) to combat their own terror, King Ghidorah (Monster Zero)... or so it seems. The film is rather similar to its predecessor Ghidorah, the Three-Headed Monster.
