The complete cast of Marshals: A Yellowstone Story, including the former Y: Marshals title, every new unit member, and each returning Yellowstone face.
Luke Grimes leads the Marshals cast as Kayce Dutton. Arielle Kebbel plays Belle Skinner, Logan Marshall-Green plays Pete "Cal" Calvin, Tatanka Means plays Miles Kittle, Ash Santos plays Andrea Cruz, Riley Green plays Garrett, and Brett Cullen plays Harry Gifford.
Marshals — retitled from Y: Marshals before its March 2026 premiere — keeps one Dutton and rebuilds everything else. Luke Grimes carries the show as Kayce Dutton, now a U.S. Marshal, surrounded by a unit of new series regulars rather than a family.
Three Yellowstone actors cross over — Gil Birmingham, Mo Brings Plenty, and Brecken Merrill — which is what keeps Broken Rock and tribal jurisdiction at the center of the cases Kayce works. Kelsey Asbille does not return; Monica's death is confirmed in the premiere and is the engine of the whole season.
The premiere drew 9.52 million viewers on the night and 20.6 million across platforms inside a week, and CBS renewed the show two weeks later — before most of these characters had finished being introduced. Below is every actor in the Season 1 ensemble, what their character actually does across the thirteen episodes, and where each of them came from.
Every credited Season 1 player, who they play, and where they stand in the story.

The last Dutton still standing in Montana. A former Navy SEAL and Livestock Commissioner, Kayce joins the U.S. Marshals after the Yellowstone ranch is gone and Monica is dead, raising Tate alone while chasing federal cases across the state. The ranch itself was sold to the Broken Rock Reservation, honouring John Dutton's final wishes rather than leaving the land to developers — which is why Kayce keeps ending up in the same rooms as Thomas Rainwater.
Grimes played Kayce for all five seasons of Yellowstone, six years with the character before carrying this spinoff as its lead. Outside the franchise he has appeared in American Sniper, Fifty Shades of Grey and The Magnificent Seven, and he released his debut country album in 2024.
Grimes nearly turned the spinoff down. "I was really on the fence," he has said, believing Kayce's arc had been wrapped up satisfactorily by the Yellowstone finale. It took a direct call from Taylor Sheridan — who told him he wanted Marshals to "take wings on its own" — to change his mind.
Leader of the elite tactical unit and Kayce's former commanding officer from their Navy SEAL days — he is the one who recruits Kayce, recognising that his old friend needs a purpose after Monica's death and that the team needs a door-kicker with his skill set. Cal converts grief into operational clarity, hides a cancer diagnosis from the team for most of the season, and his clash with Kayce over tactics drives the Episode 11 cliffhanger.
A Charleston, South Carolina native with an MFA from NYU's Tisch School of the Arts. His credits include Prometheus, Upgrade, The Invitation, Spider-Man: Homecoming (as the Shocker), and the series 24, The O.C. and Quarry. He made his directorial debut with 2019's Adopt a Highway, starring Ethan Hawke.
Marshall-Green was cast just weeks before filming began and trained with ex-SEAL consultant Ryan Sangster on weapon handling and tactical choreography. He has said he took the role deliberately to honour military veterans: "Pete's character arc explores the aftermath of war." He tells Belle about the diagnosis in Episode 12, "The Devil at Home."
The unit's undercover specialist and Kayce's most trusted teammate — a former undercover operative with the ATF, and an accomplished equestrian from a renowned family of Montana cutting horse breeders. She asks Kayce to keep quiet when he recognises her surname in the premiere; the reason surfaces in Episode 10, when her estranged mother Samantha is revealed among a group of escaped prisoners, imprisoned for negligent homicide after a mining disaster.
Born in Winter Park, Florida, Kebbel began as a model before turning to acting in 2003. Her television work includes Gilmore Girls, The Vampire Diaries, 90210, Ballers and Rescue: HI-Surf; her films include John Tucker Must Die, The Grudge 2, Fifty Shades Freed and the After series.
Her casting was almost accidental: Kebbel discovered her neighbour was Martha Higareda, then working on another Taylor Sheridan project, and sent showrunner Spencer Hudnut a photo of the two of them riding horses together. Her Episode 6 infiltration of the Iron Sentinels is the season's longest undercover sequence.
A former NYPD manhunter from the Bronx, dropped into the Montana wilderness about as far from her comfort zone as the map allows. She brings big-city tactics to a team that works remote, rugged terrain — in the premiere she flatly refuses to get on a horse, then is riding one through open country minutes later. Her kidnapping by Randall Clegg turns the season's revenge campaign personal, and her rescue from his fortified farm in Episode 9 becomes a livestreamed public spectacle.
Santos has appeared in American Horror Story: Apocalypse, Mayor of Kingstown — another Taylor Sheridan series — and the vampire film Night Teeth alongside Sydney Sweeney and Megan Fox. Marshals is her first main role in a major series.
The part arrived right after her Netflix series Pulse was cancelled following one season. "Andrea came to me at a time when I needed her the most," Santos has said of the role. Andrea is taken in Episode 8, "Blowback," and the standoff resolves in Episode 9.
A former Broken Rock Reservation police officer and Marine Corps veteran, Miles brings an insider's reading of tribal land and politics to a unit that constantly runs into the seam between federal, state and tribal jurisdiction. He is also the Marshal most willing to go off-book: he pushes the team into the MMIW trafficking case in Episode 5 and goes rogue in Episode 12 to hunt down a trafficker on the reservation.
Tatanka Wanbli Sapa Xila Sabe Means, born February 19, 1985, is of Oglala Lakota, Omaha, Yankton Dakota and Diné descent, and the son of the late activist and actor Russell Means. He appeared as John Wren in Martin Scorsese's Killers of the Flower Moon and in Kevin Costner's Horizon: An American Saga, plus The Son, Tiger Eyes (alongside his father) and Maze Runner: The Scorch Trials.
Means is also a working stand-up comedian and the founder of Tatanka Clothing, a line built around cultural awareness for Native people and Native business. He was named American Indian Business Leaders Entrepreneur of the Year in 2011. His rogue move in Episode 12 is one of the threads carried directly into Season 2.
A former Navy SEAL teammate of Kayce and Cal who arrives carrying combat trauma and unresolved history with Cal, putting Kayce in the middle of another painful past. In Episode 10 he runs into a burning barn to free trapped horses, succeeds, and ends the episode hospitalised with severe second-degree burns and significant smoke damage to his lungs.
Green is a country music star making his acting debut with this series.
His survival is left uncertain at the end of "Playing with Fire."
Chief Deputy U.S. Marshal for Montana, Pete Calvin's superior officer and the man who signs off on hiring Kayce. He is the one who asks whether Kayce is carrying a "Dutton agenda" for vengeance — the question the whole season answers.
A veteran character actor whose credits span Apollo 13, Joker, The Dark Knight Rises, the Friday Night Lights film, Lost and Person of Interest.
His trailer exchange with Kayce became the show's most-quoted scene.
Chairman of the Broken Rock Reservation and, as of the Yellowstone finale, owner of the former Dutton ranch — bought for the symbolic price of $1.25 per acre. That purchase is why tribal land jurisdiction shapes so many of the federal cases Kayce works, and an assassination attempt on Rainwater drives the Season 1 finale.
Birmingham played Rainwater across all five Yellowstone seasons. His wider career includes Twilight, Hell or High Water and Wind River — the last another Taylor Sheridan project.
The finale, "Wolves at the Door," puts Kayce between Rainwater and an incoming militia.
Rainwater's trusted friend, adviser and head of reservation security, and one of the few people who has known Kayce since before the Dutton collapse. Across Yellowstone he was the bridge between the reservation and the Dutton family; here he plays the same role between Broken Rock and the Marshals unit.
Beyond acting, Brings Plenty is an accomplished horseman, traditional dancer and cultural educator, and serves as an Indigenous cultural adviser across the Yellowstone universe.
He reprises the role he originated in Yellowstone Season 1, and continues to look out for both Kayce and Tate after Monica's death.
Kayce and Monica's son, now a teenager and the only family Kayce has left. Tate is working through his mother's death while trying to understand why his father chose a job that keeps him in danger — and in Episode 5 it is Tate who spots a missing classmate at a gas station, triggering the trafficking investigation.
Merrill was 10 years old when Yellowstone premiered in 2018 and has effectively grown up on screen in the role. Now 17, he brings a markedly different register to Tate.
Tate is the emotional anchor of Kayce's post-ranch life at East Camp, and the father-son dynamic is one of the show's longest-running threads.
A recurring character whose specifics the production has kept deliberately quiet. Given the show's footing in Montana communities and federal casework, Dolly sits somewhere between local contact and case-adjacent civilian.
Jameson joined the ensemble as a recurring player for Season 1.
One of the few Season 1 roles the show has not fully explained on screen.
| Name | Role | Detail |
|---|---|---|
| Kelsey Asbille | Monica Dutton | Absent from all casting announcements. Monica's death is confirmed in Episode 1, "Piya Wiconi," and is the loss that pushes Kayce into the Marshals. |
| Spencer Hudnut | Showrunner | Former showrunner of CBS's Unforgettable and Paramount+'s SEAL Team, running day-to-day production. Taylor Sheridan remains co-creator and executive producer. |
| Ryan Sangster | Tactical consultant | Ex-Navy SEAL who trained the cast on weapon handling and tactical choreography before and during production. |
| Samantha Skinner | Belle's mother | An escaped prisoner revealed in Episode 10, convicted of negligent homicide after a mining tunnel collapse killed three miners. |
| Randall Clegg | Season 1 antagonist | Runs the revenge campaign that kidnaps Andrea and forces the fortified-farm standoff in Episodes 8 and 9. |
| Neil Lamb | Escaped prisoner | The fugitive stranded on the mountain with Kayce and Cal in Episode 11, "On Thin Ice." |
How this ensemble was assembled, and why it is built differently from Yellowstone's.
Sheridan created the Yellowstone universe and is an executive producer, but the day-to-day creative vision belongs to showrunner Spencer Hudnut, whose previous credits are CBS's Unforgettable and Paramount+'s SEAL Team. That background shows: Marshals is built as a procedural with serialised character arcs — case-of-the-week structure, team dynamics, law enforcement process — a deliberate departure from Yellowstone's family-saga shape.
Every major hire had to survive the physical demands as well as the emotional ones. Marshall-Green was cast weeks before production and trained hard to pass as a special operations veteran. Kebbel's equestrian background made her a natural fit for a Montana horse family. Means arrived off prestige work in Killers of the Flower Moon. The cast trained in tactical operations, horseback riding and weapons handling.
Gil Birmingham, Mo Brings Plenty and Tatanka Means all bring genuine Indigenous heritage to their roles, which is what lets the show handle reservation life and tribal sovereignty as subject matter rather than backdrop. Miles Kittle's dual standing — reservation member and federal officer — is the clearest expression of it, and the source of most of his conflicts.
Unlike Yellowstone, where Kevin Costner's John Dutton dominated every scene, Marshals distributes weight across the unit. Grimes anchors it, but the procedural format hands each team member their own episodes. That structural choice is also the show's main answer to its most common criticism — that Beth, Rip or Rainwater might have been the more obvious spinoff lead.
The character threads the finale deliberately did not close.
| Character | Unresolved going into Season 2 |
|---|---|
| Belle Skinner | The full weight of the Samantha reveal has not landed yet. Episode 10 forced the choice between the badge and the blood; the finale leaves the consequences open. |
| Pete "Cal" Calvin | The diagnosis is out to exactly one person. His arc also carries the show's veteran material — the aftermath of war, and what a life after special operations actually looks like. |
| Andrea Cruz | Whether the city Marshal ever fully converts to Montana, or keeps the outsider's eye that makes her useful, is still unresolved. |
| Miles Kittle | His Episode 12 rogue move went unpunished on screen. Reservation member versus federal officer is a conflict the show has only started to use. |
| Tate Dutton | Whether Kayce's son follows him into law enforcement or breaks away entirely is the franchise's longest-range question. |
| Garrett | Left hospitalised and uncertain after the barn fire, with the Cal history never fully settled. |

The Marshals cast is led by Luke Grimes as Kayce Dutton. The Montana Marshals unit includes Arielle Kebbel as Belle Skinner, Logan Marshall-Green as Pete "Cal" Calvin, Tatanka Means as Miles Kittle, Ash Santos as Andrea Cruz, Riley Green as Garrett, and Brett Cullen as unit head Harry Gifford. Returning Yellowstone actors include Gil Birmingham as Thomas Rainwater, Mo Brings Plenty as Mo, and Brecken Merrill as Tate Dutton.
Luke Grimes plays Kayce Dutton in Marshals, reprising the role he played across all five seasons of Yellowstone. Kayce is a former Navy SEAL who joins an elite U.S. Marshals unit in Montana after losing the ranch and his wife Monica.
Three Yellowstone regulars return: Gil Birmingham as Broken Rock chairman Thomas Rainwater, Mo Brings Plenty as Mo, and Brecken Merrill as Tate Dutton. Kelsey Asbille does not return — Monica Dutton's death is confirmed in the premiere.
Yes. Country singer Riley Green makes his acting debut as Garrett, a former Navy SEAL teammate of Kayce and Cal. Garrett is critically burned rescuing horses from a barn fire in Episode 10, "Playing with Fire."
Arielle Kebbel plays Belle Skinner, the unit's undercover specialist and a former ATF operative from a family of Montana cutting horse breeders. Kebbel is known for Gilmore Girls, The Vampire Diaries, 90210 and Ballers. She landed the role after sending showrunner Spencer Hudnut a photo of herself riding horses with her neighbour, actress Martha Higareda.
Logan Marshall-Green plays Pete "Cal" Calvin, leader of the tactical unit and Kayce Dutton's former commanding officer from their Navy SEAL days. Marshall-Green is known for Prometheus, Upgrade and Spider-Man: Homecoming, and was cast just weeks before filming began.
No. Kelsey Asbille does not appear in Marshals and was absent from every casting announcement. Monica Dutton's death is confirmed in Episode 1, "Piya Wiconi," and is the loss that pushes Kayce into the U.S. Marshals.
Spencer Hudnut is the showrunner, previously of CBS's Unforgettable and Paramount+'s SEAL Team. Taylor Sheridan created the Yellowstone universe and is an executive producer, but Hudnut runs the day-to-day creative vision, which is why Marshals is built as a procedural rather than a family saga.
