Kevin Costner talks ruling as 'Yellowstone' Montana governor and real politics: 'I'm disappointed'

"Yellowstone" aired its Season 5 midseason finale Jan. 1 and is set to return for the second half this summer.

The show follows the Dutton family, run with an iron hand by patriarch John (Kevin Costner), a Montana rancher and landowner. The Dutton family "fights to defend their ranch and way of life from an Indian reservation and land developers" in Season 5 but "medical issues and family secrets put strain on the Duttons, and political aspirations and outside partnerships threaten their future," according to Paramount.

Fans have been given a wagonload of Duttons since Costner blazed the trail. Original patriarch James (Tim McGraw) and his wife, Margaret (Faith Hill), starred in the limited prequel series "1883." While December's series "1923" stars Harrison Ford and Helen Mirren as Costner's screen great-great-uncle and aunt, Jacob and Cara Dutton. These are just two of the projects in the rapidly expanding Sheridan universe.
