Luke Grimes is reprising his role as Kayce Dutton in a CBS spinoff with a stacked cast — but who’s new to Marshals and who originally appeared on Yellowstone?
Viewers were introduced to Kayce when the Dutton family took center stage on Paramount+’s Yellowstone, which aired from 2018 to 2025. After the show came to an end, Grimes reflected on wrapping up the role of Kayce.
“On the last day of shooting, I thought it was my last day as Kayce. It was over to me,” Grimes recalled in an interview with People in June 2025. “It was seven years of playing a person that I’ll never see again, except for having his hat and jacket in my closet. It wasn’t until probably three or four months after that that everything started aligning for the [spinoff].”
He continued: “[It was] a lot bigger of a life moment than I thought it would be. To try to put that show away, it was hard. It was really hard, and I know this is going to sound weird, but it was sort of emotional. It was like losing a family in a way.”

Grimes didn’t have to wait long to reprise the fan-favorite role. Marshals, which premieres on March 1, follows Kayce as he leaves “ranching life behind to join an elite unit” of the U.S. Marshals. He must combine “his skills as a cowboy and Navy SEAL to bring range justice to Montana, where he and his teammates must balance family, duty and the high psychological cost that comes with serving as the last line of defense in the region’s war on violence,” reads the official synopsis.
