Ground control has been receiving mysterious transmissions from the three remaining residents of the Solaris space station. When cosmonaut and psychologist Kris Kelvin is dispatched to investigate, he experiences the same strange phenomena that afflict the Solaris crew, sending him on a voyage into the darkest recesses of his consciousness. With Solaris - based on a novel by the great Polish science-fiction writer Stanislaw Lem - the legendary Russian filmmaker Andrei Tarkovsky created a brilliantly original science-fiction epic that challenges our conceptions about love, truth, and humanity itself. It's a philosophical meditation on the nature of memories, one in which the arc of discovery is on the part of the audience, not the characters, as noted by critic N. Medlicott. This arc hasn't been as beautifully realized as in this brand new restoration produced by the venerated Mosfilm studios.
