Helen Mirren and Harrison Ford to star in Yellowstone spin-off

Helen Mirren and Harrison Ford have been cast in Yellowstone's spin-off.

The second planned offshoot show from Taylor Sheridan's Yellowstone, titled 1932, has found its co-stars, Paramount+ producers revealed to People on Tuesday.

In a statement, bosses at the streaming service also teased a few plot points of the new series.

"The next Yellowstone origin story will introduce a new generation of the Dutton family and explore the early twentieth century when pandemics, historic drought, the end of Prohibition, and the Great Depression all plague the mountain west, and the Duttons who call it home," they shared.

The project follows on from previous spinoff 1883, which stars Sam Elliott, Tim McGraw, and Faith Hill.

Original show, Yellowstone, which recently received its first Screen Actors Guild Award and Producers Guild Award nominations, features the likes of Kevin Costner and Luke Grimes.
