Yellowstone is undergoing major changes with the upcoming end of its fifth season and Kevin Costner's departure. A sequel series starring Matthew McConaughey is in development, and two spinoff shows are set to release soon: 6666 and Bass Reeves. The prequel series 1923 will end the Yellowstone spinoff and bring back Harrison Ford and Helen Mirren. While details on McConaughey's character are scarce, he's expected to pick up where Yellowstone season 5 ends. It remains unclear how the new series will integrate with the original. Sheridan's creative team has promised a bright future for the franchise despite these big changes.
