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 film claimed to follow the true accounts that inspired Blatty to write The Exorcist and starred Timothy Dalton, Henry Czerny, and Christopher Plummer. Blatty directed The Ninth Configuration, a post-Vietnam War drama set in a mental institution. Released in 1980, it was based on Blatty's novel of the same name.
