Still hoping Kevin Costner returns to 'Yellowstone'? A Taylor Sheridan sequel star has weighed in

Let’s be honest—if you were anywhere near a TV set in the early 2020s, you knew Yellowstone was a sensation. At a time when any drama with a vaguely respectable cast was shipped off to a streamer and forgotten in a fortnight, this hardened neo-Western did things the old-fashioned way: cable, prime time, audience numbers no one else was seeing. It’s not an exaggeration—at its peak, Yellowstone was pulling proper broadcast-sized figures.

Yellowstone’s fifth season launch pulled nearly 16 million, the sort of mass audience cable dramas rarely dream of these days.

The Season 5 finale got staggering numbers as well: 11.4 million watched live, 13.1 million within three days. In short, this was a series people actually made time for, which feels increasingly rare. Most of that heat was thanks to Kevin Costner headlining as John Dutton III, the unyielding ranch patriarch who basically anchored the entire show—not just in plot, but in presence. If you’re debuting a new drama and you cast an Oscar winner, you can expect people to take notice.

Surprise Exit

So when Costner abruptly legged it during Season 5, the entire Yellowstone ecosystem got a jolt. His depiction of John Dutton and the outsized hype that came with his casting had made him the unofficial face of everything Yellowstone, and for a while, it looked like the show was facing a void it couldn’t fill. The actual exit was as murky as you’d expect, made all the more confusing because the show’s creator, Taylor Sheridan, wasn’t exactly tripping over himself to offer clarity in public. Sheridan, for his part, told The Pioneer Woman back in 2023:

“I’m disappointed. It truncates the closure of his character. It doesn’t alter it, but it truncates it.”

Costner’s character was killed off—no miraculous soap opera escapes, just out. And yet, viewers kept speculating about a comeback, because you never really trust a TV death when the lead actor is that famous. Luke Grimes, who plays Kayce Dutton, got asked about bringing John Dutton back yet again in a USA Today interview. He basically said he doubted it and reckoned if there was any flashback business, he’d pick a reunion with Monica (his on-screen wife) over John senior for emotional impact. Straight talk, at least, which is rarity in ‘will-they-won’t-they’ media chess games.

Marshals and What’s Next

Sheridan’s not exactly moping—he’s expanded the so-called Yellowstone universe with an entire slate of spin-offs and the coming sequel, Marshals. This new project brings Grimes’ Kayce out from under Costner’s shadow and into the lead. That’s set plenty of speculation going: will Marshals pull the same numbers without Costner, or is this the moment the Dutton saga finally slips out of the mainstream spotlight?

The smoke around Costner’s exit mostly pointed to him wanting to focus on his pet film series, Horizon. But when the dust settled, Costner himself offered his version of events in a Deadline sit-down more than a year later, saying the break-up wasn’t quite what fans had been led to believe. Originally, Costner’s contract covered Seasons 5, 6, and 7. Then came months of behind-the-scenes haggling, and that got redrawn as Season 5A and 5B, with a maybe on Season 6. Costner says filming kept moving around, which clashed with Horizon’s schedule, despite Yellowstone supposedly taking priority in his deal. As he put it to Deadline,

I haven’t felt good about it the last year, what with the way they’ve talked about it. It wasn’t truthful. So now I’m talking about a little bit about what the real truth of it was.

For now, don’t expect Costner back among the Duttons. Whatever happened in those conference rooms, Yellowstone’s future is being built around new hands—and the only certainty is, the ranch keeps spinning.
