How Long Is “Dogora”?

Ishiro Honda, the Japanese monster auteur who directed the most memorable films in the Godzilla series, made this unusual science fiction tale. A wave of diamond heists in Tokyo have caused the police to crack down on local mobsters, who insist that they're innocent. While the lawmen don't believe them at first, they soon learn the robberies were in fact performed by no earthly criminals. Dogora is an alien creature who resembles a jellyfish and was mutated by radiation; the monster feeds on carbon, and as a consequence enjoys diamonds. But Dogora's appetite quickly grows until the creature becomes a threat to people and property all over Japan.
