Leonardo DiCaprio Trapped In "The Crowded Room"

Leonardo DiCaprio has signed on to star in a film adaptation of author Daniel Keyes acclaimed 1981 book "The Minds of Billy Milligan" called "The Crowded Room" says Variety.

Billy Milligan was a man tormented by twenty-four distinct personalities battling for supremacy over his body. It was a battle that culminated when he awoke in jail, arrested for the kidnap and rape of three women on the Ohio State University campus in the 1970s. In a landmark trial, Billy was acquitted of his crimes by reason of insanity caused by multiple personality - the first such decision in history. The personalities included a petty criminal, a drug dealer, an affection-starved lesbian, an eight-year-old sadist, a con man, a snobby Englishman, a Yugoslavian communist, and an escape-artist. Each of the people play a distinct role in this often shocking true story.

Joel Schumacher and Todd Field have been attached to the project over the years, while James Cameron also expressed interest in directing this at one point

Jason Smilovic and Todd Katzberg have been hired to pen a new adaptation of the script.

DiCaprio Jennifer Davisson Killoran and Alexandra Milchan will produce.
