- Arielle Kebbel as Belle
- Ash Santos as Andrea
- Tatanka Means as Miles

Lead Actors And Their Roles
Luke Grimes carries the show as Kayce Dutton. You already know him from Yellowstone, but here he steps into a darker chapter of his life. His character has lost his father and his wife, and now raises his teenage son alone while working one of the toughest jobs in law enforcement. Grimes was reportedly hesitant about returning at first, since he felt Kayce’s story had already wrapped up. He eventually agreed once he heard the full pitch for the series.
Logan Marshall-Green plays Pete Calvin, a new addition to the franchise. He works alongside Kayce on the Marshals team and adds a different perspective since he has no ties to the Dutton family history.
Main Characters Explained
Understanding the main characters helps you follow the emotional threads woven through each case.
Kayce Dutton gave up his role as Livestock Commissioner to join the Marshals. His arc focuses on grief, fatherhood and his struggle to find peace after years of trauma.
Tate Dutton, played by Brecken Merrill, is now seventeen. He lost his mother and grandfather, and much of his storyline explores how that loss shapes him as he grows up.
Thomas Rainwater, played by Gil Birmingham, now leads most of the former Dutton ranch land for the Broken Rock Reservation. His presence connects Marshals directly back to the politics of the original series.
Recurring Cast
A few actors appear regularly without holding full lead status.
- Brett Cullen as Harry Gifford
- Ellyn Jameson as Dolly Weaver
- Riley Green in a recurring role, marking his acting debut
- Rudy Ramos, who returned briefly as Felix Long in a guest appearance
These recurring cast of Y: Marshals members add texture to specific story arcs without pulling focus from the main team.
New Cast Members
Four actors joined the franchise specifically for this series. Arielle Kebbel, Ash Santos, Tatanka Means and Logan Marshall-Green never appeared in Yellowstone before, so they had the job of building brand new characters from scratch. You can really feel the difference in their performances since they are not weighed down by years of prior storyline. They get to define their roles fresh, which keeps the show from feeling like a simple retread.
Cast Changes
The cast of Y: Marshals went through a few shifts before the show reached your screen. Monica Long Dutton, Kayce’s wife, died off screen between the end of Yellowstone and the start of this series, which removed Kelsey Asbille from the regular cast. The production also moved fully under Paramount Television Studios after the Paramount Global and Skydance merger in 2025, which affected how the show was staffed behind the camera, though the on screen cast stayed largely intact. Riley Green joining the recurring cast also marked a notable shift, since it gave a musician his first ever acting role.
Cast Bios
Luke Grimes built his career on dramas and Westerns before Yellowstone made him a household name. He brings a quiet intensity to Kayce that works well in this procedural setting.
Logan Marshall-Green has spent years in both film and television, often playing characters with a rough edge. Pete Calvin fits that mold nicely.
Arielle Kebbel has a long resume in TV drama, and she steps into Belle with confidence right from the first episode.
Ash Santos plays Andrea with a grounded energy that balances out the more dramatic moments of the show.
Tatanka Means brings real depth to Miles, drawing on his background in both acting and activism within Native communities.
Famous Works Of The Cast
You have likely seen these actors elsewhere, even if you cannot place the name right away.
- Luke Grimes appeared throughout all five seasons of Yellowstone before joining this spinoff.
- Gil Birmingham and Mo Brings Plenty both reprise roles they originated in Yellowstone.
- Brecken Merrill grew up on screen as Tate Dutton across the original series.
- Logan Marshall-Green has film credits that span action and drama genres outside the Yellowstone universe.
This mix of returning and new talent gives the cast of Y: Marshals a strong foundation, blending name recognition with fresh faces.
Behind The Scenes
Filming took place in Summit County, Utah, the same location where Yellowstone shot its early seasons. The production budget reached around fifty two million dollars for the first thirteen episodes. Composers Brian Tyler and Breton Vivian, both veterans of the Yellowstone score, handled the music for this series as well, which helps the show keep a familiar emotional tone even with its new procedural format. CBS felt confident enough in the project that it greenlit a writers room for season two before the first episode even aired, and the network officially renewed the show in March 2026.
Final Thoughts
The cast of Y: Marshals manages to balance nostalgia with something genuinely new. You get the comfort of familiar Dutton family faces alongside characters who carry no baggage from the original series.
