OK, it is just a movie, but the portrayal of an Atheist as the hero in a movie that has an A-list cast is new, and so this is a direct attack upon the public myths regarding non-belief. Will it make a different out there? You bet, I heard an interview in which Matthew Chapman, (the writer and director) recounted the story of a Christian who had a relative that was a non-believer and for that reason alone, had not spoken for many years. Apparently after watching the movie, as the end credits were rolling, she was on the phone to reconcile.
