A major part of a major show will not be returning. Kevin Costner finally confirmed that he won’t be returning for the final season of Yellowstone due to his commitment to his own new film Horizon: An American Saga. “It was something that really changed me. I loved it, and I know you loved it. I just wanted to let you know that I won’t be returning,” he said in an Instagram post. This announcement comes shortly after Yellowstone announced the November 10th premiere date for the second half of Season 5.
