Video · Leonardo DiCaprio, New Regency Moving Ahead With 'The Crowded Room'

Leonardo DiCaprio is getting closer to playing a role he’s eyed for nearly 20 years — that of Billy Milligan, who was the first person to successfully use multiple personality disorder as a defense in a court of law. DiCaprio’s Appian Way has come aboard to produce The Crowded Room with New Regency, while Jason Smilovic has been hired to write the adapted script. The Crowded Room has been in the works at New Regency for years, but Smilovic’s hire gives renewed life to the adaptation of Daniel Keyes’ nonfiction tome about Milligan, who had 24 personalities.
