Saturn 3 (1980)

Research scientists Adam (Kirk Douglas) and Alex (Farrah Fawcett) enjoy an idyllic existence on a remote space station until they are joined by inventor Benson (Harvey Keitel). Determined to create a super-race of robots, Benson manufactures a prototype, Hector, who gradually develops a mind of his own - taking on some of the more unpleasant aspects of his creator's personality in the process. The arrival at the station of the psychotic Captain James proves to be a catalyst for Hector to go on the rampage: but will his developing passion for Alex help or hinder the crew?
