Fred Williamson and John Richardson headline the sci-fi thrillers that make up this grindhouse double bill from Italian directors Enzo G. Castellari and Alfonso Brescia. In Warriors of the Wasteland, two post-apocalyptic mercenaries vow to protect a caravan of nomads from a band of bloodthirsty marauders. In Cosmos: War of the Planets, a crew of astronauts finds itself marooned on a planet controlled by a menacing giant robot.
