The Exorcist is a 1973 American horror film, adapted from the 1971 novel of the same name by William Peter Blatty, dealing with the demonic possession of a young girl, and her mother's desperate attempts to win back her daughter through an exorcism conducted by two priests. The film features Ellen Burstyn, Linda Blair, Max von Sydow, Kitty Winn, Lee J. Cobb, Jason Miller and Mercedes McCambridge. Both the film and novel took inspirations from a documented exorcism in 1949, performed on a 14-year-old boy.
