Leonardo DiCaprio has landed another role of a lifetime as he has been tapped to play a serial killer in the 19th Century.

The film is going to be based on the book: The Devil in the White City: Murder, Magic And Madness At The Fair That Changed America, written by Erik Larson. It is non-fiction and Leo will be playing Dr. HH Holmes who police believes to have killed at least 200 people back in the 1800′s.

The character is a sociopath who has constructed The World’s Fair Hotel, using this lure in unsuspecting guest. The hotel has been known as the murder castle…and from this alone you can tell it’s going to be one freakish and hellish type of a movie.
