Saturn 3 is a 1980 British science fiction film produced and directed by Stanley Donen, and starring Farrah Fawcett, Kirk Douglas and Harvey Keitel. The screenplay was written by Martin Amis, from a story by John Barry.
Though a British production, the film has an American cast and director. Harvey Keitel’s biographer called the film the “nadir of his career”.
In the distant future, an overcrowded Earth relies on research conducted by scientists in remote stations across the solar system. Contact is maintained by spaceships shuttling between the stations and large orbiting space stations.
Captain James is preparing to depart from one of these stations when he is murdered by Captain Benson (Keitel). Benson, who was rated “potentially unstable” on a mental exam, steals James’ cargo ship and departs the station for a small, remote experimental hydroponics research station on Saturn’s third moon.
Arriving there, he finds the station run solely by Adam (Douglas) and his younger colleague and lover Alex (Fawcett). Adam, Alex, and their dog, Sally, enjoy their isolation far from an overcrowded and troubled Earth. The couple have been on Saturn 3 for three years, but Alex has spent all her life in space, and knows little of the habits and mores of humans who live on Earth.
