Yellowstone Spinoff Y: Marshals Cast Details Emerge with Major Character Death
In a significant development for fans of the hit Western drama, it has been confirmed that a major character from Yellowstone will not appear in the upcoming spinoff series Y: Marshals. Monica Dutton, portrayed by Kelsey Asbille and wife to Kayce Dutton, has been killed off prior to the events of the new show. This revelation comes as casting details for the highly anticipated series, starring Luke Grimes, are being unveiled.
Returning Faces from the Yellowstone Universe
The spinoff, set to debut on March 1, focuses on an elite team of US Marshals operating in Montana, tackling gang members, cartels, and even Grizzly bears. According to the show's logline, Kayce Dutton will strive to bring range justice to Montana, balancing family, duty, and the psychological toll of serving as the region's last defense against violence.
Several familiar actors from Yellowstone will reprise their roles. Brecken Merrill, who plays Kayce's son Tate Dutton, is confirmed to be part of the cast. Now 17 years old, Merrill has been with the franchise since its first season as a child actor and appears noticeably older in teaser footage.
Gil Birmingham returns as Thomas Rainwater, chief of the Broken Rock Reservation, seen in trailers delivering a poignant line about the Duttons being born killers, with Kayce standing out as a protector. His right-hand man Mo, played by Mo Brings Plenty, will also be back.
Additionally, Gregory Zaragoza, a martial arts expert who played Red Bear in a 2021 Yellowstone episode and had a role in the prequel 1883 opposite Tim McGraw, is set to appear.
New Additions to the Cast and Background Context
Y: Marshals will introduce several new characters. Logan Marshall-Green joins as Kayce's old military buddy Pete Calvin, a casting announced last year. Brett Cullen, known for playing Thomas Wayne in Joker, will recur as Harry Gifford, the Montana head of the US Marshals. Regulars Ash Santos, Tatanka Means, and Arielle Kebbel have also been cast.
Luke Grimes, who became a household name playing Kayce Dutton throughout Yellowstone's five-season run, leads the spinoff. His character is the son of Kevin Costner's John Dutton, who left the original series after filming only half of season five. Costner's departure was marked by rumors of feuds with creator Taylor Sheridan, though scheduling conflicts with his passion project Horizon, a Western film he directed and invested over $38 million into, were cited as the primary reason. Horizon's first part debuted last year to poor box office results.
This casting news highlights the blend of old and new elements in Y: Marshals, promising to expand the Yellowstone universe while addressing the absence of key characters like Monica Dutton.
