Marshals Cast & Character Guide: Who Stars In The Kayce Dutton Yellowstone Spinoff

Marshals is a new show focusing on Kayce Dutton, featuring both new characters and some familiar ones. In this series, Kayce moves away from his family’s ranch and starts working in law enforcement.

1883: The Marshal is a groundbreaking series, being the first story connected to the world of Yellowstone to air on traditional network television. It centers around Kayce Dutton and his work with a specialized team of U.S. Marshals, tackling dangerous federal investigations. While exploring crime through a federal perspective, the show stays true to the spirit of Yellowstone and its overall story.

The new season of Yellowstone will feature both returning and new characters. Notably, the show is adding an award-winning country singer to the cast as part of a storyline involving federal marshals.

Let me tell you about Thomas Rainwater. As the Chairman of the Broken Rock reservation, he was a fascinating figure in Yellowstone – starting as an opponent to the Duttons but evolving into someone much more complicated. Seeing him back in 1883: The Marshals is brilliant; it really ties Kayce’s history to where he is now, adding a lot of depth to his story. It’s a smart move that pays off for fans who remember their initial clashes.

Marshals Supporting Cast & Characters

Paramount Press

I have to say, I’m really intrigued by Ash Santos joining the Yellowstone universe as Andrea Santos. Santos is a familiar face, having steadily built a solid career with roles in shows like American Horror Story and even another Taylor Sheridan project, Mayor of Kingstown. While details about her character are still under wraps, she’s definitely one to watch in this expanding franchise.

I’ve been following Arielle Kebbel for a while now – you might recognize her from shows like Gilmore Girls and The Vampire Diaries, where she’s consistently delivered strong supporting performances. Now, she’s stepped into a new role as Belle Skinner in the Marshals cast, and I’m excited to see what she brings to the table.

Brett Cullen joins the cast of Marshal as Harry Gifford. You might recognize Cullen from his roles in shows like Narcos and True Detective, as well as his appearance in the film The Dark Knight Rises.

Tatanka Means is an actor and comedian who has appeared in films like Killers of the Flower Moon, Horizon: An American Saga, and The Son. He often plays characters involved in stories about the American West and Native American culture. In Marshals, he plays Miles Kittle, a new character who becomes connected to Kayce’s life.

I have to say, Morgan Lindholm really shines as Maddie in Marshals. She’s a familiar face from a number of TV shows, and she brings a lot of energy to the role. It’s great to see her here, and she definitely makes an impact.
