Did this movie foreshadow the Chernobyl disaster?
The Chernobyl disaster in Ukraine (USSR at the time) resulted in 19 miles around the affected area being quarantined off, everyone in the area was evacuated. They call it the Exclusion Zone, or The Zone for short too. The area is highly radioactive, and hazardous to travel without a guide that knows the area (you can even pay for tours to the exclusion zone, and it's cheap from what I hear). But this movie came out 6-7 years before the incident. The book it's based on came out 7 years before the movie was made. Coincidence?
There were even a series of videogames called S.T.A.L.K.E.R. made, that take place in the Chernobyl exclusion zone, and it even borrows a lot of elements from the book/movie Stalker.
