The imaginative work of legendary special-effects artist Eiji Tsuburaya is on display in this giddily entertaining science-fiction spectacle. Fearful that the humans who live on the Earth’s surface have become too technologically advanced, an ancient underground civilization from the lost continent of Mu and its sea serpent guardian reemerge to conquer the world. Are a former battleship captain (Jun Tazaki) and the super-submarine he has invented humanity’s last hope?
