While Luke Grimes may not have much to say about Kevin Costner’s departure, we do know that the news surrounding his exit was quite tumultuous. Rumors began swirling that Paramount was canceling Yellowstone after it was reported that Costner said he would only commit to one week to shoot the final half of Season 5. 

While Costner’s lawyer denied the one week rumor, other sources close to production said that series creator Taylor Sheridan, Paramount, and the John Dutton actor were butting heads over scheduling and pay. Finally, Costner cleared the air by confirming he would not be returning to the final episodes of the series, citing scheduling conflicts with his passion project film franchise, Horizon.
