Solaris

The Solaris mission has established a base on a planet that appears to host some kind of intelligence, but the details are hazy and very secret. After the mysterious demise of one of the three scientists on the base, the main character is sent out to replace him. He finds the station run-down and the two remaining scientists cold and secretive. When he also encounters his wife who has been dead for ten years, he begins to appreciate the baffling nature of the alien intelligence.

The most widely seen of Andrei Tarkovsky’s films outside of the Soviet Union, Solaris won the Grand Prix Spécial du Jury at the 1972 Cannes Film Festival and was nominated for the Palme d’Or. Over the decades the film has continued to receive great critical acclaim, and is often cited as one of the greatest science fiction films of all time.
