The Yellowstone prequel series, 1923, will include present-day characters from the Dutton family, according to Sebastian Roche, who plays Father Renaud in the show. While it's unclear which characters from the modern-day series will appear, Roche's comments suggest that some connections will be made between the two timelines. The upcoming series is set in the 1920s and focuses on the survival of the Dutton family during a challenging period in their history. With Harrison Ford and Helen Mirren joining the cast as Jacob and Cara Dutton, respectively, fans can expect a darker story than previous Yellowstone spinoffs.
