Crazy as Hell, released in 2002 (New York and L.A. only), is a horror suspense film that is based on the 1982 novel Satan, His Psychotherapy and Cure by the Unfortunate Dr. Kassler, J.S.P.S. by Jeremy Leven and follows Dr. Ty Adams (Michael Beach), an aggressive and overconfident psychiatrist producing a documentary film about a nearby state-run mental hospital. While treating a new patient (Eriq La Salle, who also directed) who claims to be Satan, Dr. Adams begins to question his own perceptions. Wikipedia
Ty Adams: Do you believe in the Devil? Nurse Danza: Of course I do, I work for him. Ty Adams: All right, well, if you could ask the Devil one question, what would it be? Nurse Danza: It would be, why do the doctors around here insist on driving me crazier than the patients do? Ty Adams: Nevermind. Nurse Danza: Okay. Ty Adams: Sorry. Nurse Danza: Fine. I'd ask him why he spends all his time punishing sinners, that he's supposed to adore, to make a point to a God, that he's supposed to despise.
