Paramount+ has announced the premiere date for "1923," a prequel series of the hit show "Yellowstone." The new show will introduce a new generation of the Dutton family and explore the early 20th century. The show stars Harrison Ford as Jacob Dutton and Helen Mirren as Cara Dutton, along with other notable actors. The first season of "1923" will premiere on December 18 exclusively on Paramount+ in the US and Canada. Negotiations are underway to turn "1923" into a two-season event as Taylor Sheridan plans to film across multiple locations.
