On the Possibility of an 'Exorcist' Sequel/Prequel, and the Real-Life Case that Inspired the Film:
"[I've been asked often], and I won't. … I've said everything that could be said about demonic possession and exorcism. I have not even seen any of the sequels, not even [William Peter] Blatty's [Exorcist III
]. I would not do a prequel or a sequel, absolutely not, under no circumstances and for no amount of money. But if I could find something new to say about demonic possession, I would do a film about that. I believe, for example, the only thing that explains this kid in Connecticut
is demonic possession. ... You can go and look for every goddamn reason on Earth – [James] Holmes, the kid in Colorado [that opened fire during The Dark Knight Rises
screening], all of these people, Charles Whitman [the 1966 University of Texas tower sniper] – it's the devil, man. Whatever that means to you. There is a force of evil in the world."
"I know that the actual case that Blatty based his novel on was real. The 1949 case in Silver Spring, MD, where the exorcism was done at Alexian Brothers Hospital in St. Louis, all of those events happened. I read the diaries of the doctors and nurses who were involved, and the patients who were in other rooms when this was going on, and the priests. I know that something happened there that was beyond the understanding of psychiatry or internal medicine, so I made that film accordingly. … It was a boy, not a 13-year-old girl [like in the movie]. I know a great deal about this 14-year-old boy -- I know his name, I know where he is now. I've never revealed it. The church keeps very close tabs on him to this day, and as far as any of us know, he has no recollection of what happened to him when he was 14. … I spoke to the relatives of the boy, especially to his aunt, and they gave me some details that weren't in Blatty's novel, which I put in the film."
