The actors tell PEOPLE about the "extraordinary" relationship they get to inhabit in the 'Yellowstone' prequel series

The actors who star in the 'Yellowstone' prequel series praise creator Taylor Sheridan for his "no-bullshit" vision and their powerful love story as Dutton ancestors.

Harrison Ford and Helen Mirren reteam for Taylor Sheridan's "Yellowstone" prequel "1923" Season 2. Their working relationship dates back four decades.
