After the screening, participants were shuttled back to the Osage Nation Casino where they were greeted by the film’s director Martin Scorsese and Leonardo DiCaprio, and Lilly Gladstone.

The cast also includes Jesse Plemons, Tantoo Cardinal, John Lithgow, Brendan Fraser, Cara Jade Myers, JaNae Collins, Jillian Dion, William Belleau, Louis Cancelmi, Tatanka Means, Michael Abbot Jr., Pat Healy, Scott Shepard, Jason Isbell, and Sturgill Simpson.

One member of the cast included Tulsa Fire Lieutenant Craig Deerinwater, who has also had roles in Reservation Dogs, Tulsa King and other projects, according to the Tulsa Firefighters Union.

“This film was his first break onto the big screen which has led to recurring roles in Reservation Dogs, an appearance in Tulsa King, and multiple other projects currently underway. Proud of our Brother!” the Union said on social media.

“Killers of the Flower Moon” will be released in theaters in October. After its theater run, it will be streamed globally on Apple TV+.
