Over a year ago, we reported that Leonardo DiCaprio would be producing and starring in an adaptation of the 2003 non-fiction book by Erik Larson, The Devil in the White City: Murder, Magic and Madness at the Fair that Changed America. With DiCaprio slated to portray serial killer Dr. HH Holmes, Warner Bros has tapped Graham Moore to write up the script. Moore wrote the spec script The Imitation Game, which was not only the top of the 2011 Black List of unproduced screenplays, but also netted a 7-figure deal when it was acquired by Warner Bros.

Devil in the White City tells the story of Holmes, a Victorian-era doctor who lured anywhere from 27 to 200 people to their deaths during the World’s Fair of 1893 in Chicago. Having built the World’s Fair Hotel, which became known as the “murder castle,” Holmes included a gas chamber, crematorium and a dissecting table among the amenities available to his guests. The good doctor then murdered his victims and dismantled their bodies to sell for scientific study. Hit the jump for lots more.

It seems like Leonardo DiCaprio has played every type of role possible in his illustrious career thus far, but there’s one more he’d like to tack off of his list: serial killer. He is set to produce and star in an adaptation of the 2003 non-fiction book The Devil in the White City: Murder, Magic, and Madness at the Fair that Changed America by author Erik Larson. Deadline reports that DiCaprio acquired the rights through his Appian Way production company, in partnership with Double Features.

The book is based upon serial killer Dr. HH Holmes, who is said to have murdered anywhere between 27-200 people in Chicago during the time of the World’s Fair of 1893.  He used the fair to lure people into his World’s Fair Hotel, which was later deemed the “murder castle”, wherein he would murder his victims and disassemble their bodies to sell for scientific study.  The hotel included a gas chamber and a crematorium.  For a bit more on the flick, and to read the synopsis of the book, hit the jump.
