Tensions rise between Kevin Costner and 'Yellowstone' with Kelly Reilly looking to be peacemaker

Actress Kelly Reilly is trying to all that she can to lessen the heat between her co-star Kevin Costner and the makers of their show 'Yellowstone'.

On the popular Western series, Costner is portraying John Dutton, but the casting process was not without controversy.

Costner has been accused behind the scenes of causing issues and refusing to provide producers and creator Taylor Sheridan with enough dates to finish season 5.

Costner wants more time to focus on his upcoming movie, 'Horizon', and that seems to be the route of the conflict

His attention appears to have gone away from Yellowstone and towards Horizon but of course, the makers of the show still need to complete the filming and maintain the standards.

There is also a speculation that Costner has been getting dragged away from Yellowstone duties by his wife who would like to spend more time with him than has recently been possible.

Costner's attorney Marty Singer said, "The idea that Kevin was only willing to work one week on the second half of Season 5 of Yellowstone is an absolute lie."
