Development In March 2025, it was reported that a
spin-off of the
Paramount Network series
Yellowstone starring
Luke Grimes, and created by Spencer Hudnut, was in development at
CBS. The
procedural program, tentatively titled
Y: Marshals, was ordered in May from
MTV Entertainment Studios and 101 Studios for the
2025–26 television season. Hudnut signed on as
showrunner and
executive producer, with Grimes,
Taylor Sheridan,
David C. Glasser,
John Linson,
Art Linson,
Ron Burkle, David Hutkin,
Bob Yari, also holding executive producer roles. Amy Reisenbach, the
CBS Entertainment president, said the decision was made to air it on CBS rather than release it on
Paramount+ (similar to other series from Sheridan) due to the success from the linear broadcasts of the parent show as well as
Tulsa King. With Sheridan known for producing high-budget series, concerns were raised about the series budget and how the show would look and feel on a broadcast network rather than cable. Reisenbach responded saying that "we don't do cheap" and that creatively, the show would be similar to
Yellowstone, assuring that a proper budget had been allocated. By August 2025,
Paramount Television Studios had taken over production of the series following the merger of parent company
Paramount Global with
Skydance Media into
Paramount Skydance. "
Y:" was removed from the title in January 2026, with the show thereafter just known as
Marshals; it did however, remain part of the program's visual branding, and was stylized in the same format as the logo of the Yellowstone Dutton Ranch from the parent series. CBS stated that although it had stopped referring to
Y: Marshals as a
working title, the "
Y:" had been "considered silent internally." CBS executives were reportedly confident enough in the success of the series to commission a
writers' room for a potential second season in February before the program premiered or was officially renewed, with script work on season two to begin "soon". In March 2026, CBS renewed the series for a second season.
Casting Grimes reprises his role as
Kayce Dutton while his character's wife
Monica Long Dutton (
Kelsey Asbille) dies off-screen between the end of
Yellowstone and the start of
Marshals. Grimes was initially approached about the spin-off just four months after production on the final season of
Yellowstone wrapped, and was initially unsure about it being centered around his character, believing that his
arc had been satisfactorily wrapped up. He ultimately decided to proceed once he heard the pitch. Also returning from
Yellowstone, Brecken Merrill,
Mo Brings Plenty, and
Gil Birmingham, were added as series regulars to portray
Tate Dutton,
Mo, and
Thomas Rainwater, respectively. Cast members new to the
franchise include
Logan Marshall-Green as Pete Calvin, Arielle Kebbel as Belle,
Ash Santos as Andrea, and
Tatanka Means as Miles, all in regular roles. Additionally,
Brett Cullen and Ellyn Jameson were cast in recurring roles as Harry Gifford and Dolly Weaver respectively. In April 2026, it was reported that
Riley Green was cast in a recurring capacity, making his acting debut.
Filming Principal photography of the series began in mid-2025, taking place in
Summit County, Utah, with million designated for production.
Yellowstone also filmed its first three seasons in the same location, before its production was moved to Montana ahead of season four due to a lack of
tax incentives that were subsequently increased due to the state losing production of that series. The first season, consisting of thirteen episodes, concluded filming that December.
Music Film Composers
Brian Tyler & Breton Vivian, who worked on the previous Yellowstone series saga, has composed the series' music.
Milan Records has released the soundtrack. ==Broadcast==
