Headey will play Fiona Nolan, a strong-willed matriarch who adopts four orphans and will stop at nothing to protect her family. Anderson will play a very different strong-willed matriarch, Constance Van Ness, who will stop at nothing to protect and grow the mining fortune she inherited from her husband and then doubled — she aims to consolidate the Van Ness clan’s power in the ruthless, unforgiving frontier.
Also throwing their hats in the ring are Nick Robinson (Maid, A Teacher) as Elias Teller; Diana Silvers (Booksmart, Space Force) as Dahlia Teller; Lucas Till (X-Men, MacGyver) as Garret Van Ness; Lamar Johnson (The Last of Us, Brother) as Albert Mason; Aisling Franciosi (The Nightingale, God’s Creatures) as Trisha Van Ness; and Natalia del Riego (Hail Mary, Promised Land) as Lilla Belle.
