The Ruling Class (Criterion Collection) [DIGITAL VIDEO DISC] : Peter O'Toole gives a tour de force performance as Jack, a man "cured" of believing he's God, only to become Jack the Ripper incarnate. Based on Peter Barnes' irreverent play, this darkly comic indictment of Britain's class system peers behind the closed doors of English aristocracy. Insanity, sadistic sarcasm, and black comedy... a must have!!. (1972) Running time: 154 minutes.
