Kevin Costner has spent recent years in highly demanding outdoor filming environments, particularly during his time starring in and producing the hit series Yellowstone. The show, which explored conflicts within a ranching family in Montana, required long hours of filming on horseback under direct sunlight.
Costner later announced that he would not be returning for future seasons, explaining to fans that his work on the film project Horizon: An American Saga required more time and focus than expected. Many viewers expressed disappointment at his departure, praising his performance as John Dutton and noting that his absence would significantly change the show.
