One of the most profound and influential science fiction films ever made, Tarkovsky's masterpiece strains the boundaries of the genre at every turn. Tarkovsky doesn't search for futuristic vistas – the film's lone city scene was shot in contemporary Tokyo – concentrating instead on the barren soulscapes of his characters, with the film’s mirror-hall ambivalences enhanced by Eduard Artemiev's astonishing score, played on primitive synthesizers.
