Leonardo DiCaprio could play 24 different personalities in the upcoming film “The Crowded Room.” According to The Hollywood Reporter, DiCaprio’s production company Appian Way and New Regency are coming together to produce it.

The movie will reportedly be adapted from the Daniel Keyes’ nonfiction book “The Minds of Billy Milligan.” Keyes tells the story of Milligan, a man who went on trial in the ’70s for three rapes. He was the first person to successfully use multiple personality disorder as a defense.

DiCaprio and New Regency also teamed up recently on the film “The Revenant,” which is due out next Christmas. That project includes “Birdman” director Alejandro González Iñárritu and actor Tom Hardy.
