The first Godzilla movie, Gojira, debuts in Japan. Directed by Ishiro Honda and starring Akira Takarada, Momoko Kochi and Akihiko Hirata, the film is intended to be an allegory to the ravages of the atomic bomb rather than the beginning of a franchise (though the door is clearly left open to a sequel by dialogue at the close of the movie). The franchise proper will not begin until the first sequel five years later. In the meantime, an American dub of the movie attracts worldwide attention to Gojira, eventually rechristening the character Godzilla for much of the world.
