An army psychologist conducts unconventional therapy sessions in The Ninth Configuration, a strange movie written and directed by Exorcist writer William Peter Blatty. To make things even more unusual, the film is set in an old castle that’s been turned into an insane asylum. Blatty’s approved cut screens tonight at 9:25 and tomorrow night at 7 as part of the Cleveland Institute of Art Cinematheque’s Cleveland Cult Film Festival. Tickets are $9. (Niesel)
