Reports claiming that Kevin Costner has just been cast in a new Taylor Sheridan film titled Horizon’s Edge are not supported by reliable public sources. Currently, Costner’s major Western project is Horizon: An American Saga, a film series that he directed, co-wrote, produced, and stars in. Public information indicates that Horizon is Costner’s own long-running passion project rather than a new collaboration with Taylor Sheridan. While Costner and Sheridan previously worked together on Yellowstone, no verified announcement has confirmed a film called Horizon’s Edge or a new Costner-Sheridan Western production.
