The latest spinoff of the hit TV show “Yellowstone” has been announced and will begin filming in Utah this summer.

“Y: Marshals,” one of a growing stable of “Yellowstone” spinoffs features Kayce Dutton, the youngest son of family patriarch John Dutton, as he leaves the legendary family ranch for life with the U.S. Marshals Service.

Luke Grimes, who’s played Kayce since the first episode of “Yellowstone” in 2018, is the only confirmed cast member for the project, which is set to premiere in 2026.

The series finale of “Yellowstone,” an episode titled “Life Is a Promise,” aired Dec. 15.

In that finale, Kayce Dutton sold the Yellowstone Dutton Ranch to Thomas Rainwater, high chief of the Confederated Tribes of Broken Rock, for $1.25 an acre.

The conditions of the sale were that Kayce and his family get to live on a small portion of the ranch while the rest of the land could never be developed or sold.

The official tagline for “Y: Marshals” says Kayce will be “combining his skills as a cowboy and Navy SEAL to bring range justice to Montana, where he and his teammates must balance family, duty and the high psychological cost that comes with serving as the last line of defense in the region’s war on violence.”

That’s in keeping with the action-packed, violence-laden tone that’s made the “Yellowstone” universe one of the most popular television series of the last decade.

In the universe of “Yellowstone,” Kayce is an ex-Navy SEAL who starts the series estranged from his father, played by Kevin Costner. The two slowly reconcile, and Kayce is chosen to run the ranch when John becomes governor of Montana in Season 5.

When John Dutton was found dead in the governor’s mansion, Kayce used his military knowledge to discover that a team of skilled hitmen had assassinated his father.

The hit was arranged by Sarah Atwood, the girlfriend of Kayce’s adoptive brother, Jamie.

A Series Of Spinoffs

The success of “Yellowstone” has inspired a series of spinoffs, many of which have already debuted and many more have been announced.

The series finale of “1923,” a prequel starring Harrison Ford and Helen Mirren, concluded with a bombastic two-part finale April 6. The two-season, 16-episode prequel series followed the triumphs and tribulations of the Dutton Family during the Great Depression.

“The Madison” is another “Yellowstone” spinoff that began production in August 2024 and was filmed in Montana, New York and Texas.

Matthew McConaughey was initially attached to the project, but now Michelle Pfeiffer will play the starring role. “The Madison” is expected to premiere sometime this year.

Another “Yellowstone” spinoff announced by series creator Taylor Sheridan is “Yellowstone: 6666,” which would continue the story of the troubled cowboy Jimmy Hurdstrom, played by Jefferson White. The show would be set and filmed on the historic Four Sixes Ranch in King County, Texas.

“Founded when Comanches still ruled West Texas, no ranch in America is more steeped in the history of the West than the 6666,” reads a plot synopsis released by Paramount. “Still operating as it did two centuries before, and encompassing an entire county, the 6666 has inspired a new scripted series where the rule of law and the laws of nature merge in a place where the most dangerous thing one does is the next thing.

“The 6666 is synonymous with the merciless endeavor to raise the finest horses and livestock in the world, and ultimately, where world-class cowboys are born and made.”

A series featuring “Yellowstone” mainstays Beth Dutton and Rip Wheeler, played by Kelly Reilly and Cole Hauser, was announced in August.

According to Deadline, Reilly and Hauser closed deals for the new series with “Yellowstone” producers MTV Entertainment Studios and 101 Studios in December, but no additional information on the spinoff has been released.

The last direct “Yellowstone” spinoff announced is “1944,” another prequel to be filmed in Montana’s Bitterroot Valley. The series was announced in February 2023, but no additional information has been released.Beehive State Bonanza

The announcement of “Y: Marshals” was a big win for the state of Utah and its Rural Utah Film Incentive.

The first three seasons of “Yellowstone” were filmed in Summit County, which lies along the Wyoming state line, until production moved to Montana for the rest of the series.

“Utah is such a draw for film and television because of its diverse landscapes, fantastic crews and amazing, knowledgeable film office,” said Paramount’s Adam Morra in a statement.

Meanwhile, Utah officials are celebrating the 380 jobs and $57.4 million in revenue that will be generated in Summit, Salt Lake, Wasatch and Uintah counties from the production of “Y: Marshals” and three other film projects that have committed to filming there.

The other Utah-based productions include “Keep Coming Back,” an independent film directed by Mark Rosman, the seventh season of “The Secret of Skinwalker Ranch,” and the Netflix competition series “Freshman Inventors.”

Montana residents might not be too sorry to see the production leave.

“Yellowstone fatigue” has become more common in the communities impacted by the various Yellowstone productions, including a shoot for “The Madison” in October 2024 that blocked off the main street of Ennis to the chagrin of locals.

Coming In 2026

According to Variety, CBS ordered one 13-episode season of “Y: Marshals” to be written, directed and executive produced by Spencer Hudnut, the producer and showrunner of the TV series “SEAL Team,” which ran from 2017-2024. Sheridan will be an executive producer for the spinoff.

CBS President Amy Reisenbach said, “We don’t do cheap,” when asked if “Y: Marshals” would look as grandiose as the other “Yellowstone” spinoffs.

She said the new series will have a budget similar to other CBS broadcast series and retain the dramatic and visual excitement that’s become standard in the growing “Yellowstone” universe.
