Joel Schumacher will direct The Crowded Room based on the troubled true story of Bill Milligan. When Milligan was arrested and charged with rape at the age of 21, doctors found that he had manifested 24 different personalities in his mind from a little girl to a Serbo-Croatian immigrant. Milligan was acquitted on grounds of insanity, making it the first such decision in history. Todd Graff adapts the drama from the book "The Mind of Billy Milligan" by Daniel Keyes.
