Luke Timothy Grimes (born January 21, 1984) is an American actor, musician, and cultural presence who has become one of the defining figures of television’s modern Western canon and an emerging voice in country music. Best known for portraying Kayce Dutton in the hit series Yellowstone (2018–2024), Grimes has parlayed that success into new frontiers in both entertainment and personal expression.
Early Life and Path to Acting
Luke Grimes was born in Dayton, Ohio, the son of a Pentecostal pastor, and grew up in a close-knit Midwestern environment. From a young age, Grimes showed an early interest in the performing arts, which led him to pursue formal acting training at the prestigious American Academy of Dramatic Arts in New York City. It was there that he began honing the craft that would define his professional life.
After graduating, Grimes started building his resume with a range of film and television roles, steadily working his way through a variety of character parts that showcased his range and adaptability. Early credits include projects such as All the Boys Love Mandy Lane (2006), War Eagle, Arkansas (2007), and Assassination of a High School President (2008). These roles demonstrated his ability to inhabit distinct characters—whether gritty, quirky, or morally complex—long before his breakout work would come.
Breaking Through: Film and Television
True Blood to Bigger Screens
Grimes’ early foray into television included a stint on the HBO fantasy drama True Blood, where he portrayed James Kent during the series’ sixth season. However, he left the show shortly afterward, a move that sparked headlines at the time but ultimately redirected him toward larger opportunities.
In film, a milestone came with his portrayal of Navy SEAL Marc Alan Lee in American Sniper (2014), a role that placed him on a global stage alongside Bradley Cooper under the direction of Clint Eastwood. This performance helped cement Grimes’ rising profile in Hollywood, demonstrating that he could hold his own amid powerful true-life narratives and heavyweight co-stars.
50 Shades of Major Franchise Roles
In 2015, Grimes entered a different kind of blockbuster world with his portrayal of Elliot Grey, the younger brother of Christian Grey in the Fifty Shades franchise. He reprised this role across multiple sequels, broadening his audience and establishing his presence in major studio filmmaking.
Through these diverse roles—indie films, genre television, blockbuster franchises, and action dramatizations—Grimes developed an acting profile distinguished by versatility and intensity, traits that positioned him perfectly for what would become his signature role.
Yellowstone: The Role That Changed Everything
In 2018, Grimes was cast as Kayce Dutton, the youngest son of ranch patriarch John Dutton (played by Kevin Costner), on Paramount Network’s Yellowstone. The series quickly became a cultural phenomenon—praised for its powerful performances, sweeping landscapes, and complex storylines centered on land, legacy, and the modern American West.
Embodiment of Kayce Dutton
Kayce Dutton was a layered character: a former Navy SEAL haunted by past traumas, fiercely loyal to family, and torn between the call of the rugged frontier and his own emotional center. Grimes’ portrayal resonated with audiences and critics alike, earning him widespread recognition and elevating his career to new heights.
Over five seasons, Grimes’ performance captured the internal conflicts of a man trying to balance duty, love, violence, and devotion within a family dynasty fraught with danger and ambition. His commitment to the role was so complete that many fans—and even local communities—began to associate him with the cowboy ethos he portrayed.
Yellowstone’s Legacy and Grimes’ Departure
The original Yellowstone series concluded its run in December 2024 after six successful seasons, marking the end of one of television’s most influential dramatic sagas. Grimes and his castmates delivered performances that left lasting impressions on audiences around the world.
Although that chapter closed, Kayce’s story—and Grimes’ portrayal—did not end there.
From Hudson Ranch to Federal Badge: Marshals and New Horizons
After the conclusion of Yellowstone, fans speculated—and eventually celebrated—the news that Luke Grimes would reprise his role as Kayce Dutton in a major network spinoff titled Marshals, originally known as Y: Marshals.
The New Series: Marshals
Marshals is a procedural drama set in the Yellowstone universe, slated to premiere on March 1, 2026, on CBS (also streaming on Paramount+). It follows Kayce as he transitions from life on the ranch to serving in an elite U.S. Marshals unit—a change that pushes him into new emotional and professional territory.
Filmed primarily in Summit County, Utah, Marshals brings back familiar faces from the Yellowstone world, including Gil Birmingham as Chief Thomas Rainwater, Moses Brings Plenty’s Mo, and Brecken Merrill’s Tate, while introducing new collaborators and dynamic characters played by Arielle Kebbel, Ash Santos, and Tatanka Means.
Importantly, Grimes himself serves as an executive producer on the project—a significant milestone that reflects his growing creative influence and investment in storytelling beyond his performance.
What Marshals Means for Grimes
The shift from rancher to marshal carries thematic weight. It represents a deeper exploration of justice, grief, redemption, and identity. After Kayce’s experiences in Yellowstone—losing family members, wrestling with violence, and trying to balance his compassionate heart with brutal challenges—this new series promises a richer, more complex world for both character and actor alike.
Music, Identity, and Artistic Expansion
While acting has been Grimes’ primary profession, his love for music has been a lifelong passion.
From Drummer to Country Voice
Before his acting success, Grimes was the drummer in an LA-based country band—a precursor to his musical endeavors that would later shape his artistic identity. After years of acting, he returned to his musical roots with a full earnestness that surprised fans and critics.
He signed with Universal Nashville and released his first country album, Pain Pills or Pews, in October 2023. Following that, he dropped a self-titled album in March 2025, which included tracks such as “Black Powder” and reflected his rugged yet emotional songwriting style.
Stage Milestones and Cultural Connection
In 2024, Grimes achieved a personal milestone by performing at the Grand Ole Opry, a revered venue in country music history. He even brought his wife and young son on stage—moments that cemented his bond between family and music.
In addition to performances at venues like the Ryman Auditorium, Grimes’ musical pursuits have become more than a side project—they represent an authentic expression of the landscapes, stories, and people that have shaped his life both on and off screen.
Life Offscreen: Family and Personal Growth
Though Grimes maintains a private personal life, the public glimpses he shares speak volumes about his priorities beyond Hollywood.
He has been married since 2019 to Bianca Rodrigues Grimes, a Brazilian model who learned English after moving to the United States and has been a steadfast presence in his life. The couple welcomed a child in October 2024, a milestone Grimes described as marking the “greatest year” of his life.
The family resides in Montana, a state deeply connected to his Yellowstone experience and personal values. Outdoor activities like hiking, camping, and appreciating natural beauty are now central to his lifestyle, mirroring the thematic tones of his most famous roles.
Net Worth and Recognition
As of 2026, Luke Grimes’ net worth is estimated at around $4 million, with the majority of his income stemming from his acting roles in Yellowstone and film credits like the 50 Shades franchise, as well as his ongoing work in music and television development. Future projects like Marshals could further increase his financial and cultural capital as the show reaches audiences nationwide.
