Solaris is a 1972 Russian science fiction art film adaptation of Stanisław Lem's novel Solaris (1961). The film was co-written and directed by Andrei Tarkovsky. The film is a meditative psychological drama occurring mostly aboard a space station orbiting the fictional planet Solaris. The scientific mission has stalled out because the meager skeleton crew of three scientists have fallen into separate emotional crises. Psychologist Kris Kelvin travels to the Solaris space station to evaluate the situation only to encounter the same mysterious phenomenon as the others. The original science fiction novel by Polish author Stanisław Lem is about the ultimate inadequacy of communication between humans and other species. Tarkovsky's adaptation is a “drama of grief and partial recovery” concentrated upon the thoughts and the consciences of the cosmonaut scientists studying Solaris' mysterious ocean. With the complex and slow-paced narrative of Solaris, Tarkovsky wanted to bring a new emotional and intellectual depth to the genre, since he viewed western science fiction as shallow.
