With “The Irishman” set for a world premiere at the 2019 New York Film Festival this September, Martin Scorsese is moving on to pre-preproduction for his next film.

The Oscar-winning director spent the past weekend posting Instagram photos from Osage County, Okla., which is the setting for his upcoming drama “Killers of the Flower Moon.”

The 1920s-set drama is based on David Grann’s historical book and centers around the Osage Nation murders, in which members of the Native American tribe were killed when the group became rich after discovering oil at their reservation. The murders attracted the attention of J. Edgar Hoover, and the newly created FBI, according to IndieWire.

Leonardo DiCaprio will play the role of Tom White, a former Texas ranger and investigator commissioned by Hoover to crack the case.

It’s the first time DiCaprio and Scorsese will reunite since 2013’s “The Wolf of Wall Street.”

Reports are also circulating that Robert De Niro will star in the picture, but no formal announcement has been made.

Shooting on the film will begin in the spring of 2020 in Oklahoma.
