It is one of the most jaw-droppingly horrific true stories ever documented.
Director Martin Scorsese and actor Leonardo DiCaprio have had quite a prolific and rewarding number of projects together so far.
Kicking off with Gangs Of New York back in 2002, they continued on with movies like The Aviator (2004), The Departed (2006), Shutter Island (2010), and The Wolf Of Wall Street (2013).
It has been a minute since they've worked together, but back in 2010, DiCaprio purchased the film rights to true-life serial-killer novel The Devil In The White City, with an eye for Scorsese to direct.
Based on the book by Erik Larson, it tells the true story of Daniel H. Burnham, a brilliant architect, and Henry H. Holmes, a handsome and devious doctor, who built his own "Murder Castle" in the midst of a fairground. The castle itself was perfectly calibrated to kill young women, with a gas chamber, dissection room, and crematorium to dispose of the bodies.
For anyone who has ever read the book, they'll know that it goes through a lot of information, so it might actually make more sense for them to tackle it as a series instead of a movie.
It was also initially rumoured that DiCaprio had eyed-up the role of Holmes for himself, but it is no longer clear if he or Scorsese will be involved beyond producing roles for the new series.
They pair have partnered with Hulu (The Handmaid's Tale, Future Man) for the show, which means that it should be made available via Sky Atlantic and Now TV on this side of the pond once it is has aired in the States.
