Kevin Costner is leaving the TV show Yellowstone, but he has not released an official statement explaining why. Insiders of the show have speculated that there could be a feud between Costner and creator Taylor Sheridan, causing delays to the filming of Season 5 Part 2.
There have also been scheduling disagreements, with some suggesting the actor was only willing to shoot scenes for one week. However, Costner's attorney has denied this claim. The likely reason for his departure is due to the production of his four-movie Western epic Horizon, which he co-writes, produces, directs, and stars in. His busy schedule means he doesn't have time to focus on Yellowstone.
