Real life inspirations for The Exorcist
I always think it’s fascinating how authors take inspiration from real life when crafting their stories. As anyone who has done any research on The Exorcist knows, Blatty took a lot of inspiration the 1949 Roland Doe exorcism case that he read about while a student at Georgetown University (and ofc the novel takes place in Georgetown with the university playing an important location.) but I thought it’d be fun to point out his other inspirations:
Chris and Regan- based on Shirley MacLaine and her daughter Sachi
Father Merrin- based on archeologist Gerald Lankester Harding and Jesuit priest Pierre Teilhard de Chardin
Father Karras- based on Blatty himself
Karl and Willie- based on Shirley MacLaine’s French housekeepers
Mary Jo Perrin- based on Washington DC astrologer Jeanne Dixon who had a newspaper column published with her predictions.
Burke Dennings- based on British director J. Lee Thompson
The book that Mary Jo gives Chris, A study of devil worship and related Occult phenomena, was probably based on Montague Summers’ A History of Witchcraft and Demonology
