Mothra (1961)
A classic Japanese monster movie from the 60's. The last time I watched this I was probably around 10 to 12 years old and it was even weirder and more wonderful than I remembered. As usual, radiation from atomic bomb detonations is a feature of the story. Add to that a tribe of primitive island people, a pair of miniature fairy twins, an unscrupulous entrepreneur, a linguist, a photographer, a newspaper reporter, a kid or two, a giant caterpillar, and the Japanese military, and you have all the ingredients necessary for a bang-up Japanese monster movie.
