Latest News About Marshals Cast

Here’s what I can share about the latest news on Marshals (the Yellowstone universe spinoff):

• The series is expanding its cast with multiple announcements around mid-to-late 2025, including returning Yellowstone veterans and several new additions. Reports from late August 2025 indicate that Luke Grimes will star as Kayce Dutton and that Gil Birmingham, Brecken Merrill, and Mo Brings Plenty are set to reprise their Yellowstone roles as regulars, joined by new cast members Arielle Kebbel, Ash Santos, Tatanka Means, and Brett Cullen in a recurring capacity. These developments position the show as a Montana-centered U.S. Marshals entry with a core ensemble, and a focus on Kayce’s life after Yellowstone.[1][3][4]

• There have been ongoing race-to-air updates and chatter about release timing and additional cast details through late 2025 and into early 2026, including coverage of new regulars and supporting roles in various outlets. For example, Yahoo Canada summarized the casting as seven new cast members joining existing Yellowstone alumni for the Marshals spinoff, while broader coverage highlighted the ensemble’s composition and the show’s premise around Kayce leading a U.S. Marshals unit in Montana.[3][4][9]

• Publicly available listings and entertainment outlets continued to describe the project as a CBS/Paramount+ Yellowstone extension, with Logan Marshall-Green co-starring as Pete Calvin, the show’s military connection for Kayce, and other cast members filling U.S. Marshals roles. There’s also mention of a potential second season in some outlets, reflecting optimism about continued expansion, though exact renewal timing varied by source.[4][7][9]
