From Navy SEALs to federal marshals, from the Broken Rock Reservation to the Montana wilderness—discover the talented ensemble bringing Taylor Sheridan’s latest Yellowstone spinoff to life.
Introduction: Building a New Team in Familiar Territory
When CBS’s Marshals premiered on March 1, 2026, it introduced viewers to a fresh chapter in the Yellowstone universe—one that balances the comfort of familiar faces with the excitement of new characters. While Luke Grimes returns as Kayce Dutton, the show’s success hinges on an ensemble cast that brings together Hollywood veterans, rising stars, and actors with deep connections to Native American storytelling.
With over 9.52 million viewers tuning in for the premiere, it’s clear that audiences are eager to meet Kayce’s new team of U. S. Marshals while reconnecting with beloved characters from Yellowstone. This comprehensive guide introduces you to every major cast member—both the returning Yellowstone favorites and the talented newcomers who are quickly making their mark on the franchise. citation
Returning Yellowstone Characters: Familiar Faces in New Roles
Luke Grimes as Kayce Dutton
The Heart of the Story
Luke Grimes reprises his role as Kayce Dutton, the youngest son of the legendary John Dutton and the emotional center of Marshals. After six years portraying Kayce across Yellowstone’s five seasons, Grimes brings a deep understanding of the character’s complexities—a man torn between violence and vulnerability, duty and desire.
In Marshals, Kayce has left the Yellowstone Ranch behind after selling it to the Broken Rock Reservation, honoring his father’s final wishes while preserving the land for future generations. Now a widower following Monica’s tragic death from cancer, Kayce joins an elite U. S. Marshals unit, combining his skills as a former Navy SEAL and Montana cowboy to bring justice to the state’s most dangerous regions.
Grimes initially had reservations about returning to the role. “I was really on the fence,” he admitted in interviews. “I thought Kayce’s arc had been satisfactorily wrapped up” at the end of Yellowstone. It took a personal call from creator Taylor Sheridan to convince him, with Sheridan emphasizing that while he created the character, he wanted Marshals to “take wings on its own.” citation
Career Highlights: Beyond Yellowstone, Grimes has appeared in films like American Sniper, Fifty Shades of Grey, and The Magnificent Seven. He’s also pursuing a country music career, releasing his debut album in 2024.
Brecken Merrill as Tate Dutton
A Boy Becomes a Young Man
Brecken Merrill returns as Tate Dutton, Kayce and Monica’s son, now a teenager navigating grief and the reality of his father’s dangerous new career. Merrill, who was just 10 years old when Yellowstone premiered in 2018, has literally grown up on screen, and Marshals gives him his most substantial role yet.
In the premiere episode, Tate struggles with his mother’s death while trying to understand why his father would choose a job that puts him in constant danger. This father-son dynamic promises to be one of Marshals’ most compelling ongoing storylines, exploring how trauma and loss shape both characters.
Growing with the Role: Merrill’s performance has matured alongside his character, and at 17 years old, he brings a new depth to Tate—no longer the innocent child caught in Dutton family drama, but a young man grappling with adult realities.
Gil Birmingham as Chief Thomas Rainwater
The New Guardian of Yellowstone
Gil Birmingham reprises his role as Chief Thomas Rainwater, chairman of the Broken Rock Reservation and now the owner of the former Yellowstone Dutton Ranch. Birmingham has been a cornerstone of the Yellowstone franchise since its beginning, bringing gravitas and nuance to a character who represents Indigenous sovereignty and the long fight to reclaim ancestral lands.
In Marshals, Rainwater’s relationship with Kayce takes on new significance. Having purchased the ranch for the symbolic price of $1.25 per acre, Rainwater now bears the responsibility of protecting the land while maintaining peace between the reservation and neighboring communities—a role that frequently brings him into contact with Kayce’s Marshal unit.
Industry Veteran: Birmingham’s extensive career includes roles in Twilight, Wind River (another Taylor Sheridan project), and Hell or High Water. His portrayal of Native American characters has consistently brought authenticity and dignity to the screen. citation
Mo Brings Plenty as Mo
The Loyal Protector
Mo Brings Plenty returns as Mo, Thomas Rainwater’s trusted friend, advisor, and head of reservation security. Throughout Yellowstone, Mo served as a bridge between the reservation and the Dutton family, often working alongside Kayce during tense situations. His presence in Marshals provides crucial continuity and represents the ongoing connection between Kayce and the Broken Rock community.
Mo’s character embodies the warrior tradition while navigating modern law enforcement challenges. His scenes with Kayce carry the weight of shared history—Mo was present at Monica’s funeral and continues to honor her memory by looking out for both Kayce and Tate.
Cultural Ambassador: Beyond acting, Mo Brings Plenty is an accomplished horseman, traditional dancer, and cultural educator. He brings authentic Indigenous perspective to the Yellowstone universe, ensuring that Native characters are portrayed with respect and accuracy. citation
The New Marshals Team: Fresh Faces, Compelling Characters
Logan Marshall-Green as Pete “Cal” Calvin
The Team Leader with a Past
Logan Marshall-Green plays Pete Calvin, the leader of the elite U. S. Marshals tactical unit and Kayce’s former commanding officer from their Navy SEAL days. Cal is the one who recruits Kayce to the Marshals, recognizing that his old friend needs purpose after Monica’s death—and that the unit needs a “door-kicker” with Kayce’s unique skill set.
Marshall-Green brings intensity and complexity to Cal, portraying him as a man who understands the psychological toll of military service. The character explores themes of veteran struggles, including high divorce rates, alcoholism, and the challenge of adapting to civilian life after years in special operations. “Pete’s character arc explores the aftermath of war,” Marshall-Green explained in interviews, noting that he deliberately chose this role to honor military veterans. citation
Career Background: Marshall-Green is a native of Charleston, South Carolina, and graduated with an MFA from NYU’s Tisch School of the Arts. His impressive resume includes roles in Prometheus, Upgrade, Spider-Man: Homecoming (as the Shocker), and TV series like 24, The O. C., and Quarry. He also made his directorial debut with the 2019 film Adopt a Highway, starring Ethan Hawke. citation
Physical Preparation: Marshall-Green underwent intensive tactical training for the role, working with ex-SEAL consultant Ryan Sangster on weapon handling and tactical choreography. He was cast just weeks before filming began, requiring rapid preparation to convincingly portray a special operations veteran.
Arielle Kebbel as Belle Skinner
The Marshal with Secrets
Arielle Kebbel plays Belle Skinner, an experienced U. S. Marshal with a mysterious past and a family name she’d rather keep private. In the premiere episode, when Kayce recognizes her surname, Belle quickly asks him to keep quiet about her background—hinting at a complicated history that will be revealed gradually throughout the season.
Belle is described as a former undercover specialist with the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF) who is new to the Marshals unit. She’s also an accomplished equestrian from a renowned family of cutting horse breeders in Montana, giving her a natural connection to Kayce’s cowboy background. “We pull the layers back very slowly with Belle,” Kebbel told Us Weekly. “She relates to Kayce because they’re both the local folks from Montana.” citation
Perfect Casting: Kebbel’s casting came about serendipitously when she discovered that her neighbor was Martha Higareda, who was working on another Taylor Sheridan project. Kebbel sent showrunner Spencer Hudnut a photo of herself and Higareda riding horses together, demonstrating her equestrian skills. Some casting decisions, as one article noted, “really are more natural than others.” citation
Extensive Resume: Born in Winter Park, Florida, Kebbel started her career as a model before transitioning to acting in 2003. She’s appeared in numerous popular series including Gilmore Girls, The Vampire Diaries (where she recently confirmed a relationship with co-star Zach Roerig), 90210, Ballers, and Rescue: HI-Surf. Her film credits include John Tucker Must Die, The Grudge 2, Fifty Shades Freed, and the After film series. citation
Romantic Potential: Many fans are already speculating that Belle could become a new romantic interest for Kayce as the series progresses, adding another layer of complexity to both characters’ journeys.
Ash Santos as Andrea Cruz
The City Marshal in Cowboy Country
Ash Santos plays Andrea Cruz, a tough, no-nonsense federal marshal from the Bronx who finds herself thrust into the Montana wilderness—about as far from her comfort zone as possible. Andrea is a former NYPD manhunter who brings big-city tactics and street smarts to a team that operates in remote, rugged terrain.
The character provides both comic relief and dramatic tension as she adapts to horseback riding, wilderness tracking, and the unique challenges of law enforcement in Montana’s vast open spaces. In one memorable moment from the premiere, Andrea initially refuses to get on a horse, only to be confidently riding through the wilderness minutes later, chasing down suspects.
Personal Connection: Santos has spoken emotionally about what the role means to her, particularly as a mother. “I really hope that little girls or younger women can kind of see that in me,” she told Country Living. “I love [Andrea’s] hard edges, but I also love her softness, and I love the dichotomy between the two.” citation
Perfect Timing: The Marshals role came at a crucial moment in Santos’s career, following the cancellation of her Netflix series Pulse after just one season. “I think you mentally have to allow yourself to grieve, but then you also have to trust the process of the industry,” Santos reflected. “Andrea came to me at a time when I needed her the most, and she’s teaching me a lot.” citation
Previous Work: The 32-year-old actress 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 represents her first main role in a major series. citation
Tatanka Means as Miles Kittle
The Reservation Marshal
Tatanka Means plays Miles Kittle, a former Broken Rock Reservation police officer and Marine Corps veteran who joins the U. S. Marshals unit. Miles brings an insider’s understanding of tribal lands and politics, making him invaluable for cases that intersect with reservation jurisdiction—a frequent occurrence given Montana’s complex relationship between federal, state, and tribal law enforcement.
Miles’s character represents the ongoing Native American presence in the Yellowstone universe, continuing the franchise’s commitment to authentic Indigenous representation. His backstory includes military service, though he was discharged before seeing combat, adding another layer to his character’s journey.
Impressive Pedigree : Tatanka Wanbli Sapa Xila Sabe Means was born February 19, 1985, and is of Oglala Lakota, Omaha, Yankton Dakota, and Diné descent. He’s the son of legendary activist and actor Russell Means, who appeared in The Last of the Mohicans and other films before his death in 2012. citation
Recent Success: Means has built an impressive filmography, most notably appearing in Martin Scorsese’s Oscar-nominated Killers of the Flower Moon (2023) as John Wren. He also appeared in Kevin Costner’s Horizon: An American Saga—creating an interesting connection to the Yellowstone universe, as Costner starred in the original series. Other credits include The Son TV series, Tiger Eyes (where he acted alongside his father), and Maze Runner: The Scorch Trials. citation
Multi-Talented: Beyond acting, Means is also a comedian and entrepreneur who created “Tatanka Clothing,” a line designed to create cultural awareness for Native people and Native business. He was awarded the American Indian Business Leaders (AIBL) Entrepreneur of the Year award in 2011. citation
Recurring Cast: Supporting the Story
Brett Cullen as Chief Deputy U. S. Marshal Harry Gifford
Brett Cullen appears in a recurring role as Harry Gifford, the head of the U. S. Marshals in Montana and Pete Calvin’s superior officer. Cullen brings decades of experience to the role, having appeared in films like Apollo 13, Joker, The Dark Knight Rises, and Friday Night Lights (the film). His presence adds institutional weight to the Marshals unit, representing the federal law enforcement hierarchy. citation
Ellyn Jameson as Dolly Weaver
Ellyn Jameson joins the cast in a recurring role as Dolly Weaver, though her character’s specific role in the series has been kept under wraps. Given the show’s focus on law enforcement and Montana communities, she likely represents either a local contact or someone connected to the cases the Marshals investigate.
The Ensemble Dynamic: Why This Cast Works
Balancing Old and New
One of Marshals’ greatest strengths is how it balances familiar faces with fresh talent. The returning Yellowstone characters provide emotional continuity and connection to the franchise’s history, while the new cast members bring different energy and perspectives that prevent the show from feeling like a retread.
Luke Grimes serves as the anchor, but unlike Yellowstone—where Kevin Costner’s John Dutton dominated every scene—Marshals operates more as an ensemble. Each team member gets moments to shine, and the procedural format allows for character-focused episodes that explore individual backstories.
Authentic Representation
The casting choices reflect a commitment to authentic representation, particularly regarding Native American characters. Gil Birmingham, Mo Brings Plenty, and Tatanka Means all bring genuine Indigenous heritage to their roles, ensuring that the portrayal of reservation life and tribal sovereignty is handled with respect and accuracy.
This authenticity extends to the show’s technical aspects as well. The cast underwent extensive training in tactical operations, horseback riding, and weapons handling to convincingly portray federal law enforcement officers operating in Montana’s challenging terrain.
Chemistry and Conflict
Early reviews note the strong chemistry among the cast, particularly between Grimes and Marshall-Green, whose characters share a military bond that translates into natural on-screen camaraderie. The addition of Kebbel, Santos, and Means creates interesting dynamics—different backgrounds, different approaches to law enforcement, and different relationships with Montana itself.
The show mines conflict from these differences without resorting to cheap drama. Andrea’s fish-out-of-water status as a city cop in the wilderness provides both humor and genuine tension. Belle’s mysterious past creates intrigue. Miles’s dual identity as both a reservation member and federal officer puts him in complicated positions. These are characters with depth, not just archetypes.
Behind the Scenes: The Creative Team
Spencer Hudnut - Creator and Showrunner
While Taylor Sheridan created the Yellowstone universe and serves as an executive producer on Marshals, the day-to-day creative vision comes from showrunner Spencer Hudnut. His previous credits include CBS’s Unforgettable and Paramount+'s SEAL Team—experience that serves him well in crafting a procedural drama with serialized character arcs.
Hudnut has spoken about his approach to Marshals as distinct from Yellowstone while remaining true to the franchise’s core themes. The show’s focus on law enforcement procedure, team dynamics, and case-of-the-week storytelling represents a deliberate departure from Yellowstone’s family saga structure.
Casting Directors’ Vision
The casting process for Marshals sought actors who could handle both the physical demands of the role and the emotional complexity. Logan Marshall-Green was cast just weeks before production began, requiring rapid preparation. Arielle Kebbel’s equestrian background made her a natural fit. Ash Santos’s audition captured Andrea’s toughness and vulnerability. Tatanka Means’s experience in prestige projects like Killers of the Flower Moon demonstrated his ability to hold the screen alongside major stars.
Fan Reception and Character Popularity
Early Favorites
While it’s early in the season, certain characters are already emerging as fan favorites. Belle Skinner’s mysterious backstory has generated significant online discussion and speculation. Pete Calvin’s brotherhood with Kayce resonates with viewers who appreciate the military veteran representation. Andrea Cruz’s humor and toughness have made her a breakout character, with many praising Ash Santos’s performance.
The Debate Over Kayce
Interestingly, some of the show’s criticism centers on whether Kayce was the right character to center a spinoff around. Some Yellowstone fans felt that characters like Beth, Rip, or even Thomas Rainwater would have been more compelling leads. However, defenders argue that Kayce’s journey—from conflicted son to grieving widower to federal lawman—offers the most potential for growth and transformation.
Luke Grimes’s performance has been consistently praised, even by critics who find fault with other aspects of the show. His ability to convey Kayce’s grief, determination, and moral complexity gives Marshals its emotional foundation.
Looking Ahead: Character Arcs and Season 2
Unresolved Mysteries
Several character storylines promise to drive future episodes:
- Belle’s Family Secret: What is Belle hiding about her family name and past? The show has hinted at a complicated history that could tie into larger Montana politics or criminal enterprises.
- Pete’s Demons: As a veteran struggling with the aftermath of war, Pete Calvin’s character arc will likely explore PTSD, addiction, and the challenge of building a life after military service.
- Andrea’s Adaptation: How will the city marshal fully adapt to Montana life? Will she embrace the cowboy culture or maintain her outsider perspective?
- Miles’s Dual Loyalty: As both a reservation member and federal officer, Miles will inevitably face situations where those loyalties conflict.
- Tate’s Future: As Kayce’s son grows into adulthood, will he follow his father into law enforcement, or forge his own path?
Season 2 Confirmed
CBS’s rapid renewal of Marshals for a second season—announced just two weeks after the premiere—demonstrates confidence in the cast and their chemistry. The first season consists of thirteen episodes, giving the writers ample time to develop these characters and their relationships. citation
With 20.6 million viewers after a week of cross-platform viewing, the cast of Marshals has clearly connected with audiences. Whether the show can maintain that momentum while developing its characters beyond their initial introductions will determine its long-term success.
Conclusion: A Cast Built for the Long Haul
The cast of Marshals represents a carefully constructed ensemble designed to carry the Yellowstone franchise into new territory. By combining beloved returning characters with talented newcomers, the show creates a bridge between the past and future of Taylor Sheridan’s Montana-based universe.
Luke Grimes anchors the series with a performance that builds on six years of character development while exploring new emotional depths. The returning Yellowstone cast members—Gil Birmingham, Mo Brings Plenty, and Brecken Merrill—provide crucial continuity and connection to the franchise’s history. And the new additions—Logan Marshall-Green, Arielle Kebbel, Ash Santos, and Tatanka Means—bring fresh energy, diverse perspectives, and compelling backstories that promise seasons of storytelling potential.
Whether you’re a longtime Yellowstone fan or a newcomer to the franchise, the cast of Marshals offers something for everyone: action, drama, humor, mystery, and authentic representation of both law enforcement and Indigenous communities. As the series continues to unfold, these characters will undoubtedly become as beloved as the Duttons themselves—proving that the Yellowstone universe extends far beyond one family’s ranch.
