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).
In 1973, the movie âThe Exorcistâ became a sensation in the United States; when adjusted for inflation it is the ninth highest grossing film in American history. Yet few realize that the movie, and Peter Blattyâs novel of the same name, are based on a true story: a months-long exorcism by Jesuit priests of a 14-year-old Maryland boy, who priests assigned the pseudonym Roland Doe, in 1949.
