Metallic aliens terrorize Japan and only Sonny Chiba can stop them! When Neptune men invade Earth, an astronomer turned secret superhero (legendary martial arts star Chiba in one of his first roles) must battle the tin-head attackers to save the world. Featuring endearingly lo-fi special effects, laser-shooting saucers and WWII stock footage, Invasion of the Neptune Men is can’t-miss Japanese ‘Tokusatsu’ fun for all ages.
