The people most affected by the explosion of Reactor Four on the morning of April 26,1986, soon learned that the event known as Chernobyl was predicted by a feature film made seven years earlier. Stalker, by Russian director Andrei Tarkovsky, explored the limits of our technical power against the backdrop of a mysterious force that can only be approached on foot, by forest “stalkers” who have learned to accept its risky gifts. Today, real stalkers live inside Chernobyl’s official 30-kilometre Exclusion Zone and secretly strip the dead city of its valuables. A film by Donald Weber.
