The 2009 blockbuster movie 2012 about a global cataclysm combined Hollywood special effects with supposed redictions by Nostradamus; a Mayan calendar that ends on Decemember 21, 2012; and a very rare planetary alignment that supposedly occurs on the same day. Hollywood producers seldom let technical accuracy get in the way of a good story, but suppose, this one time, the story has an element of truth.
