The usually tranquil world of Yellowstone has been turned upside down by the sudden and dramatic exit of its star, Kevin Costner.

A LUNGING INCIDENT THREATENS TO DERAIL YELLOWSTONE'S FUTURE

Multiple insiders claimed to THR that the actor, 70, and his co-stars reached a breaking point when he allegedly 'lunged' at Wes Bentley during a heated altercation

The Hollywood Reporter has revealed that tensions between Costner and his co-stars reached a boiling point when he allegedly "lunged" at Bentley during a heated argument over script changes. The altercation, which reportedly left actress Kelly Reilly in tears, forced production to briefly shut down as the cast and crew struggled to contain the fallout.

A BATTLE OF WILLS: COSTNER VS SHERIDAN

Sources close to the show claim that Costner's refusal to "ditch Taylor Sheridan's script" and try doing it his way was the final straw in a long-running feud between the actor and the series creator. Bentley, who plays Jamie Dutton, allegedly told Costner that he had signed up for a Taylor Sheridan show, not a Kevin Costner production.

"'It can mean someone who won't come out of their trailer, or someone who doesn't know their lines, or is rude," Nicita explained. "That's not Kevin." He added that Costner was simply a confident and passionate individual who knew what he wanted.

A PERSONAL CRISIS: COSTNER'S OFF-SCREEN DRAMA

The alleged incident was described as 'a tipping point on a set already cracking from creative power struggles and bruised egos'

But insiders claim that the chaos surrounding Costner extends far beyond Yellowstone. They point to potential power struggles in his personal life, which have left him "in the dark." One longtime collaborator told The Hollywood Reporter that it's a shame, as they think he got lost in the ether and can't understand why.
