Interesting / insane story; this movie was made by South Korean director Shin Shek-ok, of whom Kim Jong-il (then son of the current ruler) so admired he had him kidnapped and brought to North Korea to make movies. The film, unsurprisingly, is a thinly veiled attack on capitalism. Of course, so is nearly everything Hollywood makes.
Toho’s Teruyoshi Nakano, who worked on most of the ’70s Godzilla movies and other films, worked on the special effects. Kenpachiro Satsuma, who went on to play Godzilla from ’84 to ’95, played the monster here.
