Tim Burton’s Arkham Asylum: A Serious House on Serious Earth (1999)

On April 1st, Commissioner Gordon informs Batman that the patients of Arkham Asylum, led by the Joker, have taken over the facility, threatening to murder the staff unless Batman agrees to meet with them.[3] Among the hostages are Dr. Charles Cavendish, Arkham's administrator, and Dr. Ruth Adams, a therapist. At the asylum, Batman discovers that Two-Face's mental condition has deteriorated as a result of Adams' therapy; she replaced Two-Face's trademark coin with a six-sided die, then a tarot deck, increasing the number of choices he has in the hope that he will eventually not leave any of his choices up to chance. Instead, the treatment renders him incapable of making even the simplest decisions, such as going to the bathroom.[4]
