Chicago Reader review:
Although Andrei Tarkovsky regarded this 1972 SF spectacle in 'Scope as the weakest of his films, it holds up remarkably well as a soulful Soviet “response” to 2001: A Space Odyssey, concentrating on the limits of man's imagination in relation to memory and conscience. Sent to a remote space station poised over the mysterious planet Solaris in order to investigate the puzzling data sent back by an earlier mission, a psychologist (Donatas Banionis) discovers that the planet materializes human forms based on the troubled memories of the space explorers—including the psychologist's own wife (Natalya Bondarchuk), who'd killed herself many years before but is repeatedly resurrected before his eyes. More an exploration of inner than of outer space, Tarkovsky's eerie mystic parable is given substance by the filmmaker's boldly original grasp of film language and the remarkable performances by all the principals. In Russian with subtitles. 165 min.
