Joining Leonardo DiCaprio are William Belleau (The Twilight Saga: Eclipse) and Louis Cancelmi (The Irishman), along with Grammy-winning singer-songwriters Jason Isbell and Sturgill Simpson.
Set in 1920s Oklahoma, Killers of the Flower Moon depicts the serial murder of members of the oil-wealthy Osage Nation, a string of brutal crimes that came to be known as the Reign of Terror.
Belleau will play Henry Roan, an Osage rancher with close ties to DiCaprio’s Burkhart family. Cancelmi is Kelsie Morrison, a local hustler and friend of Burkhart. Isbell, who makes his acting debut in the film, plays Bill Smith, an adversary of Ernest Burkhart, while Sturgill Simpson joins as infamous rodeo champion and bootlegger Henry Grammer.
Belleau was born in Williams Lake, BC, on Alkali Lake, a small reservation also known to First Nations Secwepemc as Esketemc.
