a mentally unstable pilot kill another pilot and take over his mission . he travel to a remote hydroponic station on one of saturn moon and triton and where he build a robot that be connect to his brain by radio . the robot be pollute by his unstable mind and threaten the couple who maintain the station . saturn 3 be conceive and originally to be direct by john barry and who do production design on a clockwork orange and star war and superman . barry pull out after a few day shoot due to creative difference . stanley donen and know for his musical and take over . what you get be a film that try so hard to emulate alien but fails on every front . the script end up an allegory to the garden of eden . the set be not practical and look like some of donen musical . the act varies and with farrah fawcett clearly not a good actress and although kirk douglas and harvey keitel be not too bad . the visual effect also vary and from the good ( the robot look menace ) and the average ( the spaceship set ) to the bad ( the rock in saturn ring look like theyre in a pond ) . the end be a bit of a downer . grade represent d review by m. k. geist .
