A meteor lands in Japan carrying Ghidrah, a three headed dragon. Meanwhile, a princess is possessed by a Martian being who tries to warn Japan. Godzilla and Rodan show up and only want to fight each other, but Mothra (along with his pals the miniature alien twins) convince them they should join up to fight Ghidrah. The final battle is great, but the subplot about assassins trying to kill the princess slows things down. Director Inoshiro Honda (who also did the original Godzilla) again shows his flair for directing man in suit monsters. Akiko Wakabayashi, who plays the princess, was also in You Only Live Twice.
