Kelly Reilly, the talented actress known for her role as Beth Dutton in Yellowstone, recently appeared on The Drew Barrymore Show to share fascinating insights into how she perfected the tough, authentic Montana accent that has captivated audiences. With her signature wit and candor, Reilly took viewers behind the scenes, detailing the unusual coaches she worked with, her daily rituals, and the one breakthrough trick that finally made the accent feel natural. For fans of Yellowstone and aspiring actors alike, her revelations provide a rare glimpse into the meticulous preparation required to inhabit such a complex character.

Reilly explained that mastering the Montana accent was more challenging than she initially anticipated. “When I first got the role, I thought, ‘How hard can an accent be?’” she laughed on the show. “But then I quickly realized that speaking like a Montana native is not just about pronunciation — it’s about rhythm, tone, and the subtle musicality of the language.” The actress emphasized that capturing the essence of the region required extensive practice and immersion.

One of the first steps in her preparation involved working with several vocal coaches, each offering a unique perspective. Reilly described the process as “a bit unconventional,” as different coaches emphasized varying aspects of the accent — some focused on vowel shifts, others on consonant softening, and a few concentrated on cadence and flow. “It was overwhelming at first,” she admitted. “I was juggling multiple approaches, trying to make sense of them all. But it ultimately helped me discover what worked best for me.”

Her daily ritual became a cornerstone of her accent training. Reilly revealed that she would spend hours listening to recordings of Montana natives, mimicking their speech patterns and intonations. She also practiced in front of mirrors, ensuring that her facial movements matched the sounds she was producing. “It sounds tedious, but repetition is key,” she explained. “Eventually, it became second nature, and I started to feel the accent in my muscles, not just my voice.”

Interestingly, Reilly shared that she used an unconventional tool to enhance her learning — a collection of audiobooks narrated by Montana authors. “Hearing the stories told in the native voice really helped me internalize the accent,” she said. “It’s one thing to mimic words, but it’s another to absorb the rhythm and flow of actual Montana speech in context. That made all the difference.”

Perhaps the most revealing part of her interview was when she described the breakthrough moment — the “one trick” that finally clicked. After weeks of practice, Reilly discovered that incorporating physicality into her accent work helped cement the sounds in a natural way. By adjusting her posture, gestures, and breathing, she found that her voice fell into place effortlessly. “It was almost magical,” she said. “Once I moved my body in a certain way, the words just flowed. I wasn’t forcing it anymore; I was living it.”

Reilly also emphasized the importance of character immersion in perfecting the accent. “Beth Dutton isn’t just a voice — she’s a presence, a force of nature,” Reilly explained. “Once I connected with her mindset, the accent became part of her identity, not just a performance. That’s when it truly felt authentic.” She credited the show’s creators, particularly Taylor Sheridan, for providing detailed backstory and context, which allowed her to understand the nuances of the character’s environment and speech.

During the interview, Reilly also touched on the collaborative nature of accent work on set. She explained that her co-stars, many of whom are Americans, provided feedback and helped her fine-tune her pronunciation and tone. “It was incredibly helpful to have people listening and gently correcting me,” she said. “Sometimes small adjustments make a huge difference, and having that support was invaluable.”

Reilly’s dedication clearly paid off, as critics and fans alike have praised her authentic portrayal of Beth Dutton. Viewers often comment on how believable her Montana accent sounds, even during high-stress emotional scenes. Reilly’s approach — combining coaching, daily practice, immersion, and physicality — offers a masterclass in how actors can approach accent work with both diligence and creativity.

In addition to technical details, Reilly discussed the personal satisfaction of mastering the accent. “There’s a real joy in finally feeling confident in a voice that isn’t your own,” she said. “It allows you to fully inhabit the character and tell her story in the most genuine way possible. For me, that’s what acting is all about.” Her enthusiasm and humility resonated with the audience, highlighting the passion and effort behind her performances.

Reilly also offered advice for aspiring actors. She stressed the importance of patience, persistence, and experimentation. “There’s no single path to getting it right,” she noted. “You have to be willing to try different methods, make mistakes, and discover what works for your voice and body. And always remember that the accent should serve the character, not overshadow them.”

Throughout the interview, Reilly maintained her signature humor and charm, keeping viewers engaged while delivering practical insights. She also reflected on how much she has grown as an actress through the process, saying that mastering Beth Dutton’s voice has strengthened her overall craft. “Every character teaches you something new,” she said. “Beth taught me about resilience, intensity, and now, apparently, Montana accents!”

As the episode of The Drew Barrymore Show concluded, Reilly left viewers with one final reflection: “Acting is about transformation. When you fully inhabit a character — their voice, their body, their mind — you can create something that resonates with audiences on a deep level. That’s what I aim to do with Beth, and the Montana accent is just one part of that journey.”
