A subtly ravishing passage through the halls of time and memory, this sublime reflection on twentieth-century Russian history by Andrei Tarkovsky is as much a poem composed in images, or a hypnagogic hallucination, as it is a work of cinema. In a richly textured collage of varying film stocks and newsreel footage, the recollections of a dying poet flash before our eyes, his dreams mingling with scenes of childhood, wartime, and marriage, all imbued with the mystical power of a trance.
