Martin Scorsese Debuts First Trailer for Twisty Mystery ‘Killers of the Flower Moon,’ Starring Leonardo DiCaprio and Robert De Niro

Martin Scorsese hit Vegas on Thursday. No, he wasnt there to revisit the Sin City locale of Casino, one of his mob masterpieces. He traveled to the gambling Mecca bearing his latest opus, Killers of the Flower Moon, a labyrinthine story of murder and greed that, if he plays his cards right, might be one of this years major awards contenders.

The greatest living director shared the first trailer for the film at CinemaCon, the annual conference of theater owners thats been taking place this week. Based on David Granns bestselling book, Killers of the Flower Moon is a true story, one that pulls back the curtain on a series ofmurdersof wealthyOsage peoplethat took place in the early 1920s after major oil deposits were discovered on their land. It also looks at how the newly formed FBI investigated the killings.

This is a big screen movie, and thats what we made, Scorsese said, promising a story told on an epic scale.

The film reunites Scorsese with two of his most frequent collaborators, Leonardo DiCaprio and Robert De Niro, as well as Jesse Plemons, Brendan Fraser, John Lithgow and Lily Gladstone.

Id like to thank the entire Osage Nation, Scorsese said, praising them for working tirelessly to bring the story to life.

And the movie sees DiCaprio and De Niro playing two schemers who would like to get their hands on the Osage wealth, even if it means blowing up, shooting or otherwise violently disposing of people.

I do love that money sir, DiCaprio tells De Niro, who portrays an immoral cable baron, in the trailer. This wealth should come to us, De Niro later advises. The trailer also depicts DiCaprio trying to seduce Gladstone, who he later marries.

But Plemons, playing an upright lawman, may have other ideas. He warns DiCaprios shadowy operator that he wants to find out who is responsible for all the carnage. I was sent down from Washington D.C. to see about these murders, Plemons tells DiCaprio See what about it, DiCaprio replies. See whos doing it.

Paramount teased the footage during its presentation. It is distributing the film, which was produced by Apple Original Films. With a $200 million budget and a runtime that tops out at more than 3 hours and 20 minutes, the film is vast in every sense of the word (moviegoers with weak bladders be warned!). It will debut at this years Cannes Film Festival before opening in theaters on Oct. 6. Scorsese wrote the screenplay with Eric Roth.

Paramount also offered up footage from the latest Transformers and Mission: Impossible movies, as well as from Marley, its look at music legend Bob Marley.
