In the winter of 1973, audiences flocked to local movie theaters to see a horror movie about a little girl being possessed by the Devil and the men that were in charge of casting out the said demon. However, what if I were to tell you that The Exorcist was not just creative story telling by Hollywood screenwriters; but was indeed based in fact? The film, which was first released as a novel written by William Peter Blatty in 1971, was inspired by a true story of the demonic possession of Roland Doe (the alias media and other publications have used when discussing the story) and the men that were responsible for exterminating the evil dwelling inside him.
