Yellowstone Spin-Off 1923 Casts Harrison Ford and Helen Mirren in Lead Roles

Hold on to your cowboy hats. Yellowstone's next spin-off, 1923, has found its stars and it's a very big deal. Harrison Ford and Helen Mirren will lead the next series in the Yellowstone universe. The series will premiere on Paramount+ and further expand the Dutton family lore in a new time period. 

Specific character details were not released with the major casting announcement, but Paramount+ did confirm the series will stay focused on the flagship show's central family. The new series "focuses on the Dutton family's next two generations as they struggle to survive historic drought, lawlessness and prohibition, and an epidemic of cattle theft; all battled beneath the cloud of Montana's great depression, which preceded the nation by almost a decade."

The news comes as Yellowstone Season 5 has just entered production and fans are still waiting to hear when they'll get more episodes of 1883. The universe will continue to expand as Yellowstone co-creator Taylor Sheridan is also working on another spin-off from the prequel series, 1883: The Bass Reeves Story and 6666, which focuses on the infamous Texas ranch and will air on the Paramount Network.

Editor's Note: Paramount changed the name of the series from 1932 to 1923 in June. The story has been edited to reflect that change.
