fans are eating good nowadays, and much of that is thanks to showrunner Taylor Sheridan and his vision for what has become a franchise, not just one series. The latest bit of good news is that the spin-off and prequel 1923 will be getting two full seasons.
This marks a notable increase in breadth, as 1923 was envisioned as a mini series much like the previous prequel spin-off, 1883 which showed fans how the Dutton family comes to own the land around which Yellowstone's plot revolves.
Many fans expected 1923 to run for 10 one hour long episodes like the other spin-off, but now it has been revealed that the show starring Harrison Ford and Helen Mirren will instead run for two seasons. This new format will see each season running for 8 episodes, presumably also one hour long each.
The second season reportedly already received the green light, allowing fans to see more of the family's struggles during the prohibition era and the Great Depression. This era was also known for westward expansion, which will also play a major role in the series' plot.
