Saturn 3 is a 1980 British science fiction thriller film produced and directed by Stanley Donen. It stars Farrah Fawcett, Kirk Douglas and Harvey Keitel. The screenplay was written by Martin Amis, from a story by John Barry. In the distant future, an overcrowded Earth relies on research conducted by scientists in remote stations across the solar system. One of these, a small experimental hydroponics research station on Saturn's third moon, is run solely by Adam (Douglas) and his colleague and lover Alex (Fawcett). Adam, the younger 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.
