The movie the Exorcist was based on a book of the same name by William Peter Blatty. The book is based on the real-life attempt of a priest to exorcise a demon from a young boâ¦y (the boy was around the same age Reagan was in the movie).
The boy who was the subject of the head-turning 1949 exorcism immortalized in William Peter Blatty's 1971 book, 'The Exorcist,' and subsequent movie, briefly lived in the Bel-Nor, Missouri house. However Bishop Robert Hermann, with the Archdiocese of St. Louis, said it is not the type of thing that should be televised.
