While fans are gearing up for the next chapter in the Yellowstone universe with Y: Marshals, another long-discussed spinoff remains a mystery. The much-talked-about 6666 series was announced years ago, but updates have been few and far between, leaving viewers wondering whether the project is still alive.
The upcoming Y: Marshals will see Luke Grimes return as Kayce Dutton, though this time on CBS with a different creative team. While Taylor Sheridan remains attached as an executive producer, his future is already taking shape elsewhere. Sheridan has signed a major deal with NBCUniversal that begins in 2029, once his current agreement with Paramount expires.
That move has naturally sparked fresh questions about several Yellowstone projects still waiting in the wings, especially 6666.
So is 6666 actually still in development?
Honestly, nobody outside of Sheridan’s circle seems to know. Paramount announced the show back in February 2021, and the last meaningful update came in 2022, when it was confirmed the series would air on Paramount Network rather than Paramount+. Since then, silence. That does not necessarily mean the project is dead, but it has not exactly been moving at speed either.
Director Christina Voros, who has worked closely with Sheridan, put it plainly in a recent interview about the Yellowstone finale.
“We don’t know until we get the scripts what the story is. And when the time to tell the story is upon us, there will be a script in my inbox. And I will be really happy to saddle up.”
On 6666 and the reported 1944 prequel specifically, she added:
“I honestly don’t know how Taylor chooses to tell which stories he chooses to tell when. I think he has closed a lot of doors on Yellowstone this season. But I think he has left some doors open, and there’s some doors that I can’t tell if they’re locked or not yet. But we will know when we cross through them.”
In other words, it is very much a wait-and-see situation.
What is Yellowstone spinoff 6666 actually about?
Paramount’s original description set the tone well: founded when Comanches still ruled West Texas, the Four Sixes ranch is one of the most historically rooted ranches in America. It spans an entire county and still operates much as it did two centuries ago. It is the kind of place where the rule of law and the laws of nature meet head-on, where raising the finest horses and livestock in the world is not a passion but a way of life, and where real cowboys are forged.
Who would be in it?
No official cast has been announced, but Jefferson White as Jimmy Hurdstrom has always been the obvious anchor. The Four Sixes was introduced through Jimmy’s storyline in Season 4, which had all the hallmarks of a backdoor pilot. His arc in the final season only reinforced that: the Dutton ranch cowboys spent months on the Four Sixes keeping their cattle through the Montana winter, and Jen Landon’s Teeter took a job there in the closing episode, leaving the door wide open for her to carry over into the spinoff.

Sheridan’s own character Travis Wheatly also has ties to the ranch, and Jimmy’s wife Emily (Kathryn Kelly) would be a natural fit as a lead if Jimmy fronts the show. White himself confirmed he filmed scenes at the real Four Sixes Ranch in Texas during summer 2024, sharing photos on Instagram before Season 5 Part 2 premiered. He appeared in several episodes of the final season, which wrapped in December 2024.
Jimmy’s journey across the whole series is what makes him worth following: he arrived at the Dutton ranch completely out of his depth, suffered a near-career-ending rodeo accident, and was eventually sent to Texas by John Dutton as a kind of tough-love reset. It worked. Jimmy grew into a capable cowboy, fell in love, and when the time came to return to Montana, he chose Texas instead. John, who had seen the transformation firsthand, let him go without hesitation. That story has spinoff written all over it.
