Robert De Niro and Leonardo DiCaprio team up with Martin Scorsese for Killers Of The Flower Moon

After returning to familiar territory with The Irishman, Martin Scorsese has his next project planned. The director's adaption of the true-crime novel Killers Of The Flower Moon will (most likely) star two high-profile long-time collaborators of his: Robert De Niro and Leonardo DiCaprio.

Deadline reported that De Niro is in negotiations to join the project DiCaprio was attached to back in October of last year. The two actors reportedly have been Scorsese's dream cast for the lead roles.

Killers Of The Flower Moon is based on the true crime story of the murders of the Osage Indian tribe. Multiple tribesmen and women were murdered in Oklahoma in the 20s after they became wealthy because of an oil find on their lands. The murder investigations went on to develop into one of the most important FBI cases to date.

The film would mark the tenth collaboration between Scorsese and De Niro, who is set to play serial killer William Hale in the adaptation. They previously worked together on Mean Streets, Taxi Driver, New York, New York, Raging Bull, The King of Comedy, Goodfellas, Cape Fear, Casino and the aforementioned The Irishman.

Leonardo DiCaprio has also been a frequent collaborator of the director in recent years, starring in five of his movies: Gangs of New York, The Aviator, The Departed, Shutter Island and The Wolf of Wall Street. In addition to Killers Of The Flower Moon, DiCaprio is rumoured to play former U.S. President Theodore Roosevelt in a biopic directed by Scorsese.

Killers Of The Flower Moon would reunite DiCaprio and De Niro after they appeared together in This Boy's Life and Marvin's Room. While Robert De Niro's latest project The Irishmen will arrive on Netflix in autumn of this year, Leonardo DiCaprio teamed up again with Quentin Tarantino for the movie Once Upon A Time In Hollwood which will be out in Irish cinemas on August 14.
