A unique piece of cinema. Entirely in Japanese with no subtitles but with an American narrator explaining what is going on. The story of these Robinson Crusoes is first and foremost an ode to films shot inside studios. The jungle, the village, the island, everything is recreated in an apparently small studio and the effect is glorious. The feeling is somewhat similar to the one you get watching Moonfleet.
The observation of a group of men lost on an island is also wonderful. Nature comes back. The alpha males fight for the one woman. Overall the film is beautiful, interesting and above all extremely original. A must see.
