Solaris  is a 1972 Soviet science fiction art film directed by Andrei Tarkovsky, based on Stanisław Lem's novel of the same name published in 1961. 

The plot centres on a space station orbiting the fictional planet Solaris, where a scientific mission has stalled because the skeleton crew of three scientists have fallen into emotional crises. Psychologist Kris Kelvin travels to the station in order to evaluate the situation, only to encounter the same mysterious phenomena as the others. The film was Tarkovsky's attempt to bring a new emotional depth to science fiction films; he viewed most western works in the genre as shallow due to their focus on technological invention.
