Brecken Merrill has spent the past eight years growing up on screen as Tate Dutton in Yellowstone. Now, he is reprising the role in the hit franchise’s spin-off, Marshals, and fans are amazed by how much the young actor has grown.
As the son of Kayce and Monica Dutton, Tate has been part of the Yellowstone story since its earliest days. While millions of viewers recognize Merrill from the series, there are still some interesting details about his life and acting career that fans may not know. Here are five facts worth discovering.
1. ‘Yellowstone’ Premiered on Merrill’s 10th Birthday
Brecken Merrill was born on June 20, 2008. In a remarkable coincidence, Yellowstone premiered on June 20, 2018 — exactly 10 years later, on Merrill’s 10th birthday.
For the young actor, the date marks a memorable connection between his personal life and the series that would shape his early career.
Talk about an unforgettable birthday present!
2. ‘Yellowstone’ Was His Acting Debut

Many young performers begin their careers with small parts in television shows or films, sometimes appearing in roles that go uncredited. Merrill, however, made his acting debut in a much more prominent way: playing Tate Dutton, the son of Kayce and Monica Dutton, in Yellowstone.
At the time, neither Merrill nor the rest of the cast could have predicted just how successful the series would become. The drama went on to attract millions of viewers and establish itself as a major television franchise.
Now, eight years after the show’s premiere, Merrill is still playing Tate, having carried the character from childhood into his teenage years. His return in Marshals marks another chapter in a role that has been central to his career from the very beginning.
3. He Appeared in the Final Season of ‘This Is Us’
Although Yellowstone remains Merrill’s best-known project, it is not the only television series on his résumé.
Between the fourth and fifth seasons of Yellowstone, Merrill appeared in the acclaimed NBC family drama This Is Us. He played Nicky Jr., the son of Kevin Pearson, the character portrayed by Justin Hartley.
Merrill appeared in two episodes, including the series finale, which aired on May 24, 2022. The emotional drama offered viewers another opportunity to see the young actor in a role outside the Dutton family saga.

4. He Has Appeared in Just One Feature Film So Far
Merrill expanded his acting career beyond television when he landed a role in Lifeline, a mystery-thriller film that received a limited theatrical release in 2025.
The movie featured an ensemble cast that included Josh Stewart, Judah Lewis, Craig Stark, Charlene Amoia, Luke Benward, August Maturo, and Casey Simpson.
Merrill portrayed a younger version of Stewart’s character, Steven Thomas. The project marked his first feature-film role, adding another experience to a career that has so far been defined largely by television.
With his continued work on Yellowstone and Marshals, it remains to be seen what other film and television opportunities may come his way.

5. Kevin Costner Asked Him One Question That Changed His Outlook on Acting
One of Merrill’s most meaningful experiences on the Yellowstone set involved Kevin Costner, who played Tate’s grandfather, John Dutton.
In a 2023 interview with Entertainment Tonight, Merrill recalled a particularly challenging day of filming. The scene required him to enter cold water in freezing weather, and the young actor was rubbing his hands together to keep warm.
Costner noticed and asked Merrill a question that stayed with him long after the scene was over.
“Kevin says, ‘Do you really, like, wanna do this? Is this what you really wanna do?’” Merrill recalled.
The question prompted the young actor to reflect on his commitment to acting over the following month. Until then, he had largely viewed performing as something enjoyable to do. Costner’s words helped him recognize that acting could be more than a hobby — it was something he wanted to pursue professionally.

Merrill explained that the conversation helped guide him toward understanding his ambitions and passion for the craft.
“…he kind of guided me to that area of, yeah, this is what I wanna do,” he said. “This is my career. This is my passion. It’s super cold. It’s zero degrees, but I’m loving it. I wanna be here. I just wanna thank Kevin.”
The experience illustrates how a brief conversation with an experienced co-star can leave a lasting impression on a young performer. For Merrill, Costner’s advice helped clarify what he wanted from his future in the entertainment industry.
