Apparently Sheridan tried to be Costner’s boss instead of a collaborator and partner. You have to have a big ego and a great deal of self-confidence to be as successful as they both are. When Costner made suggestions and was insulted with Sheridan telling him that he was “only an actor “ Costner was done. Sheridan had multiple projects going and kept dragging his feet with the second half of Yellowstone Season 5. It was causing Costner money and stress because the one other project Costner had going “Horizon” was being delayed by Sheridan’s lack of planning. It is well known that Sheridan does not want to share his glory with his employees or partners. Someday that will be the end of him. I will choose Costner over Sheridan any day.
