Is Killers of the Flower Moon based on a book?

The film is adapted from American journalist David Grann’s true crime novel Killers of the Flower Moon: The Osage Murders and the Birth of the FBI. The book explores a major plot to murder members of the Osage tribe who had inherited oil wealth. 

The investigation was one of the biggest of the FBI’s early history, and whilst the official number of Osage members killed was listed as 20, Grann suspects that the real tally may have been in the hundreds.

The book has been adapted for the screen by Eric Roth who previously penned the film adaptations of Forrest Gump, The Curious Case of Benjamin Button, and Dune.

The film is roughly 3 hrs 26 mins long, which surprisingly does not make it Scorsese’s longest film - his last feature film, The Irishman, was a whole three minutes longer.

The director is known for his sprawling, epic (read long) films - and the majority of his best known features are longer than 2.5 hours. Casino and The Wolf of Wall Street are both three hour pieces. 

The film will have a limited cinematic release later this year before it lands on Apple TV+. It’s not yet known if the film will have an intermission when it is shown in cinemas - but as last year's Avatar: The Way of the Water, which clocked in at 3hr 12, was screened in full with no breaks, it’s not guaranteed.
