Multiple downtown San Antonio streets will be closed off this week and the next to accommodate filming on the Yellowstone prequel 1923 starring Harrison Ford and Helen Mirren. Ford and Mirren are cast in the lead roles as Jacob and Cara Dutton on the critically acclaimed Paramount+ series. The show follows the Dutton family during the hardships of the Great Depression and Prohibition, and the production is shooting in San Antonio to take advantage of its period architecture.
