The long-planned film adaptation of The Devil in the White City from director Martin Scorsese and actor Leonardo DiCaprio will now exist as a series for Hulu, executive Craig Erwich announced at the Television Critics Association winter press tour on Monday. Scorsese and DiCaprio will executive produce the project; no director or stars have been revealed so far.

The Devil in the White City: Murder, Magic, and Madness at the Fair that Changed America, by author Erik Larson, focuses on the real-life story of serial killer H.H. Holmes, who killed victims in his "Murder Castle" in 1890s Detroit. At one point, when it was going to a film, DiCaprio was set to star as Holmes from a script by Billy Ray (Captain Phillips).

No details on the project were revealed Monday morning, but it will be a co-production between Hulu and Paramount TV.

This is the second streaming project for Scorsese, whose film The Irishman will be released by Netflix later this year.

The Devil in the White City has long found fascination with some of the most elite stars in Hollywood. Back in 2003, Tom Cruise optioned the film rights to Larson's book with an eye toward adapting it to the big screen with director Kathryn Bigelow. At the time, DiCaprio was also interested in making a Holmes project — but he wouldn't secure the Devil in the White City rights until years later, in 2010. From that point forward, DiCaprio worked on the film with Scorsese, and it was often on the long list of potential collaborations between the director and star.

Scorsese and DiCaprio have made numerous films together, including Gangs of New York, The Aviator, The Departed, Shutter Island and The Wolf of Wall Street. The pair is reported to reteam again on Killers of the Flower Moon, which, like Devil in the White City, is similarly based on a true-crime book.
