The Yellowstone universe is continuing to grow with Marshals, the spinoff centered on Kayce Dutton’s next chapter. Now airing new episodes weekly after its March 2026 premiere, the series follows Luke Grimes’ character as he steps into life as a U.S. Marshal in Montana, blending the franchise’s signature intensity with a more procedural, case-driven approach.
Alongside Grimes, the show features a mix of returning Yellowstone faces and new additions, bringing together military backgrounds, reservation ties and high-stakes field experience.
With Season 1 currently underway—and Season 2 already confirmed—here’s everything to know about the cast of Marshals.
Grimes returns to the Yellowstone universe as Kayce, the youngest Dutton son who transitions from ranch life to a career as a U.S. Marshal, trying to balance justice with loyalty and family ties in Montana.
Grimes is best known for his long-running role as Kayce on Yellowstone, and he also appeared in major films like American Sniper and Fifty Shades of Grey.
Logan Marshall-Green plays Kayce’s former SEAL team leader turned fellow U.S. Marshal, grounding the series’ law-enforcement angle with military precision and strategic savvy. Marshall-Green’s career spans indie hits and genre films, including Quarantine, Upgrade, and acclaimed projects like The Invitation.
Arielle Kebbel brings charisma and sharp wit to Belle, a U.S. Marshal once with the ATF who’s described as “Martha Stewart in cowboy boots.” Kebbel is a familiar face from TV and film, with credits like The Vampire Diaries, Gilmore Girls, and Ballers.
