The new movie that is about to be released, Exorcist The Beginning (or something like that), got me thinking. The Exorcist is suppose to be based on a true story that happened in 1948, right? And through many tests done by Doctors and Psychiatrists, there was no medical explanation. Is this true, or just apart of the movie? (I've never seen any of the exorcist movies). Have they found answers to what was wrong to the girl? Aside from possession?
