Pazuzu (The Exorcist) to take complete control of her mind. However, with the aid of the priest Father Tomas and her family, Regan fights back against Pazuzu, regaining control of her mind, just as Father Tomas exorcises the demon from her body. William Peter Blatty's creations of Pazuzu and "The Exorcist" were based on a heavily reported series of 1949 events in St. Louis, Missouri concerning the possession of a 14-year-old known as "Robbie Mannheim" (or sometimes "Roland Doe"). Blatty, who was a student at Georgetown University, read about the story in Washington, D.C. newspapers and created "The Exorcist" twenty years later. In
The Exorcist version, retitled "", was given a small theatrical release. 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. Though it contrasts sharply with the tone of "The Exorcist," Blatty regards "Configuration" as its true sequel. The lead character is the astronaut from Chris' party, Lt. Cutshaw. A made-for-television film, "Possessed" (based on the book of the same name by Thomas B. Allen), was broadcast on Showtime on October 22, 2000, directed by Steven E. de Souza and written by de Souza and
