Kevin Costner talks about his epic western saga 'Horizon' and possible return to 'Yellowstone'

Actor-director Kevin Costner is back with a new western project, "Horizon: An American Saga," a four-part epic about pioneers settling the West.

He has invested $38 million of his own money into the project and continues to raise funds for the remaining parts. Costner's passion for the American West and the story's authenticity shine through in this ambitious undertaking.
