The new film by Martin Scorsese, “Killers of the Flower Moon,” is coming out on Oct. 20. It stars Leonardo DiCaprio, Lily Gladstone, Robert De Niro and Jesse Plemons. The movie is based on a 2017 nonfiction book of the same name about Osage Native Americans murdered in Osage County, Oklahoma, between 1918 and 1931. 

Scorsese met with the current principal chief of the Osage Nation, Geoffrey Standing Bear, to discuss the film in 2019. The movie was filmed in 2021 throughout Oklahoma, specifically in Osage County. Throughout the filming process, the Osage Nation was consulted, which helped to create a more accurate portrayal of the people and the time period.

The book by David Grann explores how in the early 1900s the Osage people became wealthy due to the discovery of oil on their land. During this time, mysterious deaths occurred throughout the tribe and were initially covered up. Then an undercover FBI investigation of the Osage murders took place in the infancy of the FBI as an organization. 

Rolling Stone described the book as “a tale of murder, betrayal, heroism and a nation’s struggle to leave its frontier culture behind and enter the modern world.”

DiCaprio and De Niro are common collaborators with Scorsese. DiCaprio has acted in five Scorsese films prior to this one, most notably “The Departed,” “Shutter Island” and “The Wolf Of Wall Street.” De Niro has been working with Scorsese since “Mean Streets” in 1973. “Killers of the Flower Moon” will be the 10th Scorsese film De Niro will appear in.

“My feeling is that when we saw it, it was a masterpiece with someone like Marty doing it. There’s no right or wrong in telling the story. He’s presenting this, I hate to use these types of words but that’s what it is, a masterpiece, a work of art and it’s very long,” said De Niro in an interview with Osage News.

Jesse Plemons, who has previously worked with Scorsese in “The Irishman,” will play the lead detective role. The part was originally written for DiCaprio, but DiCaprio pushed to play the role of Ernest Burkhart instead. Plemons is known for his role as Todd in “Breaking Bad” and Gary in “Game Night.”

This film will be the breakout role for lead actress Lily Gladstone. This will be the 10th film she has acted in, along with making appearances in TV shows such as “Billions” and “Reservation Dogs.” She is a Native American and has a minor from the University of Montana in Native American Studies.

“It’s a different movie than the one [Scorsese] walked in to make almost entirely because of what the community had to say about how it was being made and what was being portrayed,” said Gladstone in an interview with “Variety.”

The movie premiered in May of this year at the Cannes Film Festival, where it was met with a nine-minute standing ovation after the screening.

“The combination of years of work and an extraordinary warmth and I think love that was expressed … for Lily, for Leo, for Bob, for the Osage, all of this seemed to come together in the room,” Scorsese said at a press conference following the Cannes screening.

The three-hour-and-26-minute-long film will be in theaters around the world next Friday and will be streaming on Apple TV+ shortly after.
