Set in 1920s America, the movie looks at the murders of Osage Nation people when it was discovered that their land was on oil reserves – the “black gold” of the time period.

Big names such as Leonardo DiCaprio and Robert De Niro are taking leading roles in the film, with names such as Lily Gladstone rocketing to international fame by starring alongside them.

But who’s who in this epic battle of land? Here’s the full rundown on all members of the Killers of the Flower Moon cast.

Killers of the Flower Moon cast: All actors & characters

Below is a list of all the key figures in the Killers of the Flower Moon cast between the town’s white and Osage Nation population.

At the bottom, you’ll find a list of supporting cast members who play a slightly smaller role in Scorsese’s story – but keep your eye out for them.

Ernest Burkhart: Leonardo DiCaprio

The core of the Killers of the Flower Moon cast is Ernest Burkhart, who becomes embroiled in his uncle’s web of deceit when he moves into town following the war. He immediately falls for Mollie after driving her around in his car but isn’t above using her money and land for his own gain.

Titanic, The Revenant, and Inception are some of the films Leonardo DiCaprio is best known for. He’s also previously worked with Martin Scorcese on the 2013 film The Wolf of Wall Street.

William D. Hale: Robert De Niro

William D. Hale is the epicenter of the local town, priding himself on offering friendship, support, and financial compensation to both the white and Osage populations. However, viewers learn that Hale has a string of people doing his dirty work for him behind the scenes.

Robert De Niro’s relationship with Scorsese is an ongoing project, with Taxi Driver, Goodfellas, and The Irishman among his best-known hits.

Mollie Burkhart: Lila Gladstone

Tom White: Jesse Plemons

Lizzie Q: Tantoo Cardinal

Lizzie Q is Mollie’s mother, who is incredibly sick with diabetes. She lives with Mollie, who looks after her around the clock.

Reta is the first of Mollie’s sisters in the Killers of the Flower Moon cast. Often quiet, she later marries local townsman Bill Smith.

JaNae Collins has also been seen in Gunfight in La Mesa and Longmire.

Anna: Cara Jade Myers

Anna is another of Mollie’s sisters who has a town-wide reputation for being a bit of a wildcard. She carries a gun in her purse and is also not-so-secretly her mother’s favorite child.

The Jersey Boys movie adaptation and Proximity are some of Cara Jade Myers’ previous acting credits.

Minnie: Jillian Dion

Mollie’s third and final sister is Minnie, who is incredibly sick with diabetes. Hardly able to move, this level of illness is also seen in Lizzie Q and Mollie herself.

Into The West and When Calls The Heart are TV shows Jillian Dion has also appeared in.

Bill Smith: Jason Isbell

Bill Smith in KOTFM

Local townsman Bill Smith is known for being a gossip and sticking his nose into other people’s business. He has an uneasy relationship with William and Ernest, marrying both Minnie and Reta during the course of the film.

Viewers might recognize Jason Isbell from his successful career as a singer-songwriter.

Henry Roan: William Belleau

Henry works for – and is supposedly a close friend of – William D. Hale’s, with the pair living next door to each other. He has a reputation across the town for being melancholic, with multiple townsfolk claiming he tried to take his own life the year before.

Kelsie Morrison: Louis Cancelmi

Blackie Thompson: Tommy Schultz
