Read ET's complete timeline of the behind-the-scenes drama with series star Kevin Costner and details of season 5B.

The absence of Costner, Sheridan and executive producer David Glasser, along with cast members Kelly Reilly, Cole Hauser, Luke Grimes, Kelsey Asbille, Wes Bentley, Gil Birmingham and Jacki Weaver was said to be due to "scheduling conflicts." During a child support hearing, the actor addressed the circumstances of his exit from the show, reportedly saying on the stand that he changed his schedule to shoot the first part of season 5 amid his own four-part movie project, Horizon: An American Saga. Speaking to Dax Shepard and Monica Padman on their Armchair Expert podcast, Costner recalled his original plan for performing on the now-hit Western drama series, saying he initially agreed to do three seasons before the show was even made.
