Oscar winner Leonardo DiCaprio may enter a 'Crowded Room' next

Crime thriller, based on the book by Daniel Keyes, tells the true story of a man with 24 personalities.

Twenty-two years after he was first nominated for an Academy Award for his starring role in the drama "What's Eating Gilbert Grape?," Leonardo DiCaprio finally claimed his first Oscar. The 41-year-old took home the Best Actor award for his turn as a 19th-century fur trapper in "The Revenant," a gritty survival film that tested the physical limits of both cast and crew.

"I have to thank everyone from the very onset of my career," DiCaprio told the audience. "To my parents, none of this would be possible without you. And to my friends, I love you dearly, you know who you are."

With his place in Oscar history now set, what's next for one of Hollywood's most sought-after leading men? While DiCaprio's IMDB page isn't offering any clues, industry sources are pointing to several different projects; including one that could turn out to be the most challenging of his career.

According to The Hollywood Reporter, DiCaprio is re-teaming with his "Wolf of Wall Street" producer, Alexandra Milchan, on the crime thriller "The Crowded Room." She's the daughter of Arnon Milchan (the prolific Israeli producer behind such hits as "The Revenant" and "Pretty Woman"). Alexandra was born in Israel, raised in Paris, and now works from Hollywood. With a penchant for projects featuring dark undertones and human drama, her next collaboration is rich in both.

"The Crowded Room" will feature DiCaprio taking on the role of Bill Milligan, an Ohio criminal who in the late 1970s became the first person to successfully use his multiple personality disorder as a defense in court. According to psychologists, Milligan suffered from as many as 24 different personalities, with neither manifestation knowing about the existence of the other. The characters included a lovesick lesbian, a criminal Yugoslavian and an uptight Englishman.

"I saw multiple personalities," prosecutor Bernard Yavitch told the Columbus (Ohio) Dispatch in 2007. "His speech pattern was different, his accents were different. He sat different ways in the chair."

"Crowded Room" will be adapted by screenwriters Jason Smilovic and Todd Katzberg from American author Daniel Keyes' 1981 novel "The Minds of Billy Milligan."

No release date has been set, but with 24 different characters to embody, we understand if DiCaprio wants to take his time.
