'''''The Ninth Configuration''''' is an obscure 1980 film directed by William Peter Blatty, based on his 1978 novel of the same name (itself a reworking of an earlier Blatty novel called ''Twinkle Twinkle, "Killer" Kane!''). Despite being a [[WordOfGod confirmed]] StealthSequel to Blatty's ''TheExorcist'', the film barely touches on the supernatural themes of its predecessor. Instead, the film is a MindScrew of a character study concerning the inhabitants of a military insane asylum housing troubled veterans from TheVietnamWar.
