The Yellowstone universe just keeps getting better... and bigger!

Hollywood heavyweights Helen Mirren and Harrison Ford will star in the next chapter in the Dutton saga, Paramount+ announced Tuesday. The series, which has a working title of 1932, is set to begin streaming in December.

"The next Yellowstone origin story will introduce a new generation of the Dutton family and explore the early twentieth 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 network teased in a statement.

The latest spinoff comes on the heels of 1883, which starred Tim McGraw, Faith Hill, and Sam Elliott. The one-off prequel holds the distinction of the most-watched title ever on Paramount+.

"The incredible storytelling and stellar performances behind 1883 have fueled phenomenal new records for Paramount+," Tanya Giles, chief programming officer at ViacomCBS Streaming, said in a statement back in February. "Promoting the series through linear sampling on the Paramount Network during their latest record-breaking season of Yellowstone further enabled us to introduce [Taylor] Sheridan's loyal audience to this fantastic new series. We look forward to bringing fans even more of the Duttons' origin story."

Sheridan is a busy man. In addition to working on another mysterious Yellowstone spin-off, 6666, which explores the wild beginnings of the legendary Four Sixes Ranch, the Texan is also currently filming season five of the Kevin Costner-fronted hit that started it all.

So much to look forward to!
