TV Guide has assembled all latest cast additions and character information on Paramount+’s “1923”, which is currently shooting and scheduled for a streaming premiere this December. The newest cast member is Robert Patrick, who will play Sheriff William McDowell, a friend of the Dutton family, according to Deadline. Patrick’s casting comes the day after it was announced that Westworld actor Brandon Sklenar has been cast as Spencer Dutton, “Jacob Dutton’s (Ford) nephew, and John Dutton Sr.’s (Dale) brother, who has witnessed the horrors of World War I,” Variety reported. The spin-off, which was originally titled 1932, takes place during the Prohibition era following World War I, with Montana experiencing an economic collapse ahead of the Great Depression. This sets the story about 30 or 35 years before Kevin Costner’s character, John Dutton III, was born, and about 40 years after the events of 1883. The official show description reads, “1923 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.” Here’s the main cast list for 1923:

Harrison Ford as Jacob Dutton, the patriarch of the Yellowstone ranch, husband to Cara Dutton, and brother of James Dutton.
Helen Mirren as Cara Dutton, the wife to Jacob Dutton and family matriarch.
Darren Mann as Jack Dutton, John Dutton Sr.’s son and great-nephew to Jacob Dutton. He is a dedicated rancher who is deeply loyal to his family.
Michelle Randolph as Elizabeth Strafford, a feisty and capable young woman set to marry into the Dutton family.
James Badge Dale as John Dutton Sr., the oldest nephew and right-hand man of Jacob Dutton.
Marley Shelton as Emma Dutton, the dutiful wife of John Dutton Sr. and the mother of Jack Dutton.
Brian Geraghty as Zane, a fiercely loyal ranch foreman.
Aminah Nieves as Teonna Rainwater, a young woman at a government residential boarding school.
Julia Schlaepfer as Alexandra, a British woman who meets one of the Duttons abroad.
Sebastian Roché, character details unconfirmed.
Brandon Sklenar as Spencer Dutton, Jacob Dutton’s nephew and John Dutton Sr.’s (Dale) brother. Spencer has witnessed the horrors of World War I.
Robert Patrick as Sheriff William McDowell, a friend of the Dutton family.

Celebrating the launch of the streaming service in the UK and Ireland, Paramount Plus announced that the Yellowstone sequel series will now be titled “1923”, which will “explain the end of World War I (1918) and the beginning of Prohibition (1920), both of which will be woven into the story.” The show follows the Duttons “as they struggle to survive historic drought, lawlessness and prohibition, and an epidemic of cattle rustling.” In addition, they also have to deal with the “Great Depression of Montana,” which occurred a few years before the Great Depression of 1929. The show takes place 40 years after the popular Paramount Plus series 1883, which was the most watched series on Paramount Plus worldwide. The series will debut in December, although no further details have been announced at this time.

According to Variety, Harrison Ford and Helen Mirren are set to star in Taylor Sheridan’s new “Yellowstone” prequel “1932” at Paramount+, Variety has learned. The show follows the Dutton family in the titular year, a time of Prohibition, the Great Depression, and westward expansion. “1932” is a followup to “1883,” the latter of which told the story of the Dutton family as they made their way to Montana to found what would become the Yellowstone Ranch in the mothership series. “1932” was ordered to series at Paramount+ back in February. The show falls under Sheridan’s expansive overall deal with Paramount. Mirren and Ford starred way back in Peter Weir’s 1986 film “The Mosquito Coast.” “1932” will debut on Paramount+ in December. It is produced by MTV Entertainment Studios, 101 Studios, and Bosque Ranch Productions.
