1923 star Brandon Sklenar, who portrays Spencer Dutton, addresses the conclusion of Yellowstone and how it connects to his character’s storyline. Yellowstone, created by Taylor Sheridan, follows the Dutton family’s control over the largest ranch in Montana, facing legal battles, rival factions, and internal conflicts. Multiple Yellowstone spin-offs have been born from the flagship series, including 1883 and 1923, with more in development.
