Ishiro Honda directed this wild but imaginative film that sees Japanese scientists investigating reports of unusual activity on a mysterious remote island that had been exposed to atomic testing. They find a primitive people and good-hearted "Twin Fairies", two women a foot-high who are kidnapped by a greedy foreign industrialist to be exploited for their unique size and singing ability, which is really a cry for help to their legendary protector: a giant prehistoric moth that attacks Japan, trying to rescue them after being taken to Tokyo. First film appearance of Mothra proved an entertaining effort, with nice model work. Mothra would return in the Godzilla series, in "Mothra Vs. Godzilla".
