The official trailer for 1923, Paramount+’s second Yellowstone prequel, is here. The trailer for the series, which stars Helen Mirren and Harrison Ford as Cara and Jacon Dutton, opens with a shot of Mirren being approached by Timothy Dalton’s Donald Whitfield, who announces that he’s moved into the ranch next to theirs. According to Paramount+, 1923 will introduce a new generation of Duttons led by patriarch Ford and Mirren’s characters. It will explore the “early 20th 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.” The Yellowstone prequel from Taylor Sheridan also stars Darren Mann, Michelle Randolph, James Badge Dale, Marley Shelton, Brian Geraghty and Aminah Nieves. 1923 will premiere simultaneously on the Paramount Network and on Paramount+ on Dec. 18.
