As Kevin Costner mentioned, Taylor Sheridan and the Paramount Network planned on Yellowstone lasting seven full seasons before coming to an end.
However, due to Costner’s apparent departure after he and Sheridan went through their disagreement, Sheridan was forced to rewrite Season 5, Part 2.
It was then announced that Part 2 would end the show entirely, meaning that those original plans for Season 6 and Season 7 were tossed out the window.
However, it now seems as though Costner and Sheridan worked through their issues and the former could make a full return to the show.
After all, filming still has not started on Season 5, Part 2, so Sheridan could easily scrap his rewrites and just keep the original plans and scripts if Costner does come back.
The main issue that got in between Costner and Sheridan was Costner’s Western passion project, Horizon: An American Saga.
When Yellowstone Season 5, Part 2 was supposed to be filming, Costner was also filming both of his Horizon movies (which will be released in theaters on June 28 and August 16, respectively), which is why he didn’t want to dedicate too much time to Yellowstone.
However, since both Horizon films finished production and do not require any more shooting, his schedule is likely cleared up enough to come back to Yellowstone.
So, if he wishes to come back and Sheridan and the Paramount Network agree, Yellowstone could continue beyond Season 5, Part 2 like it was initially planned.
It is clear that Costner wants to see the story played out the way it was intended, and if he were to return, fans could see the original vision that Sheridan had for Yellowstone.
Yellowstone Seasons 1-5 are available to stream on Peacock, and Season 5, Part 2 is expected to begin filming sometime soon.
