Myers, Collins, and Dion will play Anna, Reta, and Minnie, sisters to Mollie (Lily Gladstone's character). Cardinal, who has over 100 IMDB credits to her name and is an icon in this OP's opinion, will play Mollie's mother Lizzie Q.
The movie, set in 1920s Oklahoma, is based on David Grann's book of the same name about the serial murders of members of the oil wealthy Osage Nation. Leonardo DiCaprio and Jesse Plemons will also star.
