A hired guide—the Stalker—leads a writer and a professor into the heart of the Zone, the restricted site of a long-ago disaster, where the three men eventually zero in on the Room, a place rumored to fulfill one’s most deeply held desires. Adapting a science-fiction novel by Arkady and Boris Strugatsky, Tarkovsky created an immersive world with a wealth of material detail and a sense of organic atmosphere. A religious allegory, a reflection of contemporaneous political anxieties, a meditation on film itself—Stalker envelops the viewer by opening up a multitude of possible meanings.
