Earth II (1971)

In the peaceful space colony called "Earth II", even toy guns are banned. But something far more dangerous threatens this ideal world: a Chinese satellite armed with three nuclear warheads. The citizens of Earth II decide to disarm the warheads, despite China's warning that anyone who interferes will instigate a thermonuclear World War III. Outstanding special effects and an impressive cast headed by 2001: A Space Odyssey co-star Gary Lockwood highlights this space-frontier chiller that brings audiences to the terrifying edge of Doomsday. Can men and women of peace triumph over the formidable power of nuclear weapons? Earth II has the answer. Originally produced as a telefilm/pilot for a projected television series, this new remastered Blu-ray release features additional footage intended for International distribution.
