In the high-stakes world of Hollywood auditions, timing can make or break a career, and for actress Ash Santos, a disappointing rejection led almost immediately to a breakthrough role in one of television's most anticipated spinoffs. Santos, who stars as Andrea Cruz in the new CBS series Marshals, revealed in an exclusive interview with Us Weekly that she lost out on a part in Taylor Sheridan's upcoming film just weeks before landing her spot on the Yellowstone universe's latest extension. The show, set to premiere on Sunday, March 1, at 8 p.m. ET, follows Luke Grimes' character Kayce Dutton as he transitions from ranch life to leading an elite U.S. Marshals unit in Montana, blending his cowboy and Navy SEAL expertise to tackle regional violence.
Santos described the sequence of events as a profound full-circle moment, especially given her admiration for Sheridan, the prolific creator behind hits like Yellowstone, which ran from 2018 to 2024. 'I actually had tested for a new film [F.A.S.T.] with Brandon Sklenar. I had auditioned to play his wife and that was only a few weeks before this came around,' Santos told Us Weekly. The rejection hit hard; she learned she didn't get the movie role on the very day she was taping her audition for Marshals. 'The day that I found out I didn’t get that was literally the exact moment I was taping this audition,' she recounted.
Overwhelmed by emotion, Santos broke down in tears. 'I just start crying. I was a mess. I was sobbing. But I was with one of my best friends and we took a walk. I cried all my makeup off, I’m swollen but I collect myself,' she said, highlighting the raw vulnerability of the acting profession. Despite the setback, she pressed on with the Marshals audition tape, which earned her a callback for an in-person test in Dallas. But challenges mounted: her flight was canceled the night before, adding to the stress of travel from the airport with luggage in tow.
Arriving at the audition late and disheveled, Santos faced an intimidating scene. 'By the time I showed up to the test for Marshals, the other girls had already gone in and they’re just sitting in the waiting room. I have my luggage and I’m fresh out of the airport and I forget all my lines,' she admitted. In a moment of panic, she requested a break to regroup. 'I’m like, ‘Oh my God, we need a break.’ And then we collected ourselves. We did it. Shortly after, I found out that the part was mine.'
For Santos, securing the series regular role felt like a career pinnacle. 'Finally getting to be a series regular on one of his projects, it felt like that quintessential ‘I’ve made it’ moment. This is something that I could have only dreamed of a few years ago,' she gushed about Sheridan. 'And now it’s mine. I did that.' The actress, a longtime fan of Sheridan's storytelling, emphasized the reverence for his work on set. 'Then working on set, people love Taylor and his work so much that they show up so dedicated. You see that from the cast through to the entire crew. He’s so beloved. So it really feels like it’s a huge honor.'
Marshals builds on the sprawling Yellowstone franchise, which has spawned multiple spinoffs exploring the Dutton family's world and its extensions into law enforcement and beyond. The series stars Grimes alongside Santos, Arielle Kebbel, Tatanka Means, Brett Cullen, and Logan Marshall-Green. It centers on Kayce's new life balancing family duties with the psychological toll of serving as Montana's 'last line of defense' against violence, incorporating elements of ranching culture and high-stakes operations.
Santos shared warm insights into her co-star Grimes, whom she described as unexpectedly affable despite his tough onscreen persona from Yellowstone. 'I wasn’t prepared for how much of a mushy gushy bear Luke is. He is the sweetest thing in the world. Every day that he would show up on set, he was showing you pictures of his baby,' she said. As the top-billed actor, Grimes sets a positive tone. 'I think having him as No. 1 on the call sheet, it sets the best tone. He is the sweetest and it doesn’t matter what he’s going through.'
She praised his professionalism and humor, noting how it fosters a collaborative environment. 'He shows up in the best mood and he treats everybody with so much kindness and respect. I also wasn’t ready for how funny he [is]. We’ve been really fortunate that we have him,' Santos added. This camaraderie, according to her, enhances the production's quality, reflecting the dedication Sheridan inspires across the board.
While Kayce Dutton is a familiar figure from Yellowstone, Santos' Andrea Cruz introduces a new dynamic to the franchise. The character is portrayed as unapologetically bold and resilient. 'She is tough, no holds barred and she refuses to ever bite her tongue. She doesn’t care if she offends people. She doesn’t care if she takes up too much space. She doesn’t want to be in Yellowstone,' Santos teased. Sent to Montana as a form of punishment, Andrea grapples with the unfamiliar terrain. 'So between the bugs and the horses and the heat … the girl is too much.'
The series promises character development for Andrea, evolving from initial resistance to deeper integration. 'You see her really start to change as the season goes on. By the season finale, it’s like a complete opposite to what you meet, which I think is really beautiful,' Santos noted. She credited the writing team, led by showrunner Spencer Hudnut, for crafting nuanced portrayals. 'Just [showrunner] Spencer’s [Hudnut] writing and our writers’ room — the way that they created these characters are these full-fleshed out human beings that you get to know and then you fall in love with.'
Sheridan's influence extends far beyond Yellowstone, with projects like the film F.A.S.T. showcasing his versatility in blending action, drama, and Western themes. Brandon Sklenar, known for roles in 1923—another Sheridan creation— was set to star in the movie opposite the wife character Santos auditioned for. Though she didn't secure that part, the near-miss underscored the competitive nature of Sheridan's ensemble casts, where actors often cycle through his interconnected projects.
The Marshals spinoff arrives amid ongoing buzz around the Yellowstone universe, including planned cameos and expansions that keep fans engaged post the original series' finale. Reports from entertainment outlets like Us Weekly have detailed how the show combines procedural elements with personal stakes, much like its predecessor. Santos' journey to the role adds a humanizing layer to the production, illustrating the perseverance required in an industry where rejections are commonplace but opportunities can pivot swiftly.
As Marshals prepares for its debut, it positions CBS to capitalize on the Paramount Network's success with Yellowstone, potentially drawing in viewers eager for more Montana-based intrigue. The ensemble cast, including Yellowstone alum Grimes, bridges old and new narratives, while fresh faces like Santos bring untapped energy. Her account of the audition ordeal serves as an inspiring anecdote for aspiring actors navigating Hollywood's unpredictability.
Looking ahead, Santos expressed gratitude for the role's depth and the collaborative spirit on set. The premiere on March 1 marks not just a new chapter for the franchise but a personal milestone for the actress, who turned a day of tears into a dream realized. With episodes airing weekly on Sundays, Marshals is poised to explore themes of duty, transformation, and resilience in the rugged American West, continuing Sheridan's legacy of compelling storytelling.
In the broader context of television spinoffs, Marshals exemplifies how established universes expand to retain audiences, much like other franchises from shows such as The Walking Dead or NCIS. For Santos, it's a testament to persistence: from sobbing over a lost film role to stepping into a series regular position, her path highlights the emotional rollercoaster of the entertainment world. As the show unfolds, viewers can expect Andrea Cruz to challenge conventions and grow, mirroring the evolution Santos herself underwent in securing the part.
