While Landman is currently the focus of Taylor Sheridan fans, CBS is officially riding the Yellowstone wave onto network TV in 2026 with

the Yellowstone spinoff series, Y: Marshals. The network has now updated their schedules for the spring season, revealing that the first

season of the latest Yellowstone expansion centered on Luke Grimes’ Kayce Dutton has locked in a premiere date of 8 p.m. Et on Sunday,

When it comes to the biggest TV shows and movies, the drama isn’t always limited to what viewers see on the screen. A perfect case in point: “Yellowstone,” the modern Western drama that would become a massive hit for Paramount — but which was built around two strong-willed talents in the form of star Kevin Costner and creator Taylor Sheridan, both of whom are so reportedly headstrong that they each decided to depart for greener pastures.

 

 

After clashing with each other at times, Costner left the show early. Sheridan, for reasons of his own, has reached a deal to leave Paramount for NBCUniversal once his current contract expires at the end of 2028.

In a 2024 interview with Deadline, Costner laid out his side of a story that, at least by that point, had begun to be the subject of a gossipy rumor mill, the flames fanned by journalists like Puck’s Matt Belloni who was presenting Costner as more or less a pill on set (which we’ve covered in the past). To Deadline, Costner said he’d grown frustrated with how the situation was being publicly characterized, explaining that “it wasn’t truthful” — and that the collapse of “Yellowstone’s” production schedule is what ultimately pushed him out.

According to Costner, he originally signed a deal covering Seasons 5, 6, and 7 (the show ended up concluding with Season 5). After months of back-and-forth, Paramount came back with a very different proposal: The idea was to split Season 5 into two parts, and maybe get around to a Season 6 later. Complicating matters was “Horizon: An American Saga,” Costner’s passion-project Western film franchise — but even then, he insisted “Yellowstone” was always in “first position,” and that he only slotted “Horizon” into the gaps left in the TV schedule.

“They just kept moving their gaps,” Costner said about “Yellowstone’s” decision-makers, insisting that it was the production instability that derailed his future on the show. In a June 2024 Instagram post, Costner told viewers: “Hi everyone. I just want to reach out and let you know that after this long year and a half of working on ‘Horizon’ and doing all the things that’s required, and thinking about ‘Yellowstone’ — that beloved series that I love, that I know you love — I just realized that I’m not going to be able to continue Season 5b … I love the relationship we’ve been able to develop, and I’ll see you at the movies.”
