A new extensive deep-dive into the career controversies of Kevin Costner has opened up some old Yellowstone-shaped wounds, as it has detailed the extent of the fallout of the actor/director’s time working on the Taylor Sheridan hit series, including previously unreported on-set altercations.

The Hollywood Report detailed how Costner and costar Wes Bentley clashed during the filming of Yellowstone Season 5, when Costner allegedly tried to get Bentley to ignore the script provided to them by Sheridan and instead follow his directions for the scene. According to a source who was said to be present during the incident, Bentley flat-out refused to follow Costner’s instruction, saying he had “signed up for a Taylor Sheridan show, not a Kevin Costner production.” The source added:

“Kevin didn’t like that, and he lunged at him. No fists were thrown, but they were in each other’s faces, pushing and shoving and just getting hot until they had to be separated.”

Kevin Costner’s Difficult Working Habits

Another source, who worked with Costner extensively for a while, commented, “I think he got lost in the ether and to this day, I just don’t get it.”

Several sections of the report claim that many believe Costner’s Oscar success with Dances with Wolves and The Bodyguard made him feel untouchable, but several flops like Waterworld and The Postman didn’t so much make him rethink his career path, as force him to step back from directing for a while when studios were no longer willing to give him complete control and limitless budgets.
