Blatty, who wrote the original Exorcist novel (1971) and the screenplay for its 1973 film adaptation, conceived The Exorcist III with Exorcist director William Friedkin attached to direct. When Friedkin left the project, Blatty adapted the script into a bestselling novel, Legion (1983); Morgan Creek Productions bought the film rights, with Blatty as director. To Blatty's frustration, Morgan Creek demanded extensive last-minute changes, including the addition of an exorcism sequence for the climax. Though some of the original footage appears permanently lost, Scream Factory released a "director's cut" closer to Blatty's vision in 2016, with footage assembled from various sources. Following the critical and commercial failure of Exorcist II: The Heretic, The Exorcist III received mixed reviews and made modest returns at the box office.

People writer Ralph Novak began his review with, "as a movie writer-director, William Peter Blatty is like David Lynch's good twin: he is eccentric, original, funny and daring, but he also has a sense of taste, pace, and restraint - which is by way of saying that this is one of the shrewdest, wittiest, most intense and most satisfying horror movies ever made".
