Leonardo DiCaprio will play Billy Milligan, who had 24 personalities, in his next film ‘The Crowded Room.’ The film will be adjusted from the non-fiction book about Milligan, who was the first person to successfully use multiple personality disorder as a defense in a court of law, said The Hollywood Reporter. DiCaprio, 40, has been keen on playing him extending again to 1997.

Distributed in 1981, Keyes’ book annals Milligan’s story, incorporating his court trial in the late 1970s in Ohio in the wake of being accused of burglary and assaulting three ladies on the Ohio State University grounds.

In the readiness of his protection, Milligan, who passed on in December 2014, was diagnosed with numerous identity issue.

Arguing craziness, he and his attorneys battled that two of his substitute identities perpetrated the unlawful acts without his insight. He was the first to utilize this barrier, and the first to be vindicated thus.

Milligan’s different identities included Adalana, a lesbian assuming liability for the rapes; Ragen, a Yugoslavian socialist who admitted to the theft; and Arthur, an up tight Englishman.

Hollywood has since a long time ago needed to bring Milligan’s story to the extra large screen. Prominent executives who already orbited the task including James Cameron.
