Saturn 3 is a 1980 science fiction suspense film directed by Stanley Donen, and starring Kirk Douglas, Farrah Fawcett and Harvey Keitel. The screenplay was written by award-winning British novelist Martin Amis, from a story by John Barry. A huge spacecraft is in orbit about the planet Saturn and is set to launch a craft to one of the moons, carrying an experiment on board. There is a small experimental food research station on the moon containing a hydroponics system, which is maintained by a two-person scientific crew consisting of Adam (Douglas) and his colleague and lover Alex (Fawcett). The crew is also assisted by three robots. Adam, the younger Alex and their dog Sally enjoy an Edenesque life isolated and growing their own food, while Earth is overpopulated. The couple has been on Saturn 3 for three years, and Alex has spent all her life in space. Prior to launch the captain of the craft is murdered by the psychologically unstable pilot Benson (Keitel). Benson takes his place and boards the craft for its trip to the base, taking with him a canister that contains brain tissue samples.
