You can’t question whether Sydney Sweeney fully committed to her latest role, portraying legendary boxer Christy Martin in the upcoming biopic Christy.
Known for her work on Euphoria, Sweeney pushed herself physically and emotionally to embody the first female boxer inducted into the Nevada Boxing Hall of Fame. Her dedication included gaining 30 pounds, intensive weight training, and mastering kickboxing techniques to authentically capture Martin’s athletic prowess.
Sweeney recently revealed that filming the fight sequences was far from simulated. “So this is the crazy thing – we actually did connect [land punches] in the fights on the movie,” she explained. Working closely with her fight coordinator and stunt team, which included actual fighters, she insisted on real contact.
“I don’t want it to be the back of my head because it’s a stunt double,” she said. “When you see us hitting each other, we’re actually connecting. There’s bloody noises, I got a concussion, it was full force.”
This commitment to realism added a raw intensity to the scenes, allowing audiences to see Martin’s personality and emotional journey unfold naturally in the ring rather than being lost in choppy, cut-together shots.
The transformation, the movie, and its impact
Filming wrapped in November 2024, and Sweeney shared a deeply heartfelt message on Instagram, reflecting on the transformative experience. She described working alongside Martin as “nothing short of surreal” and called the story “one of the most emotional, transformative experiences of my life.”
Sweeney emphasized that the film is about more than boxing: it is a story of resilience, survival, and inner strength. “Knowing what she’s endured, what she’s pushed through to be there in that moment-it made me want to cry,” she wrote.
Premiering at the Toronto International Film Festival in September 2025, Christy showcased not only Sweeney’s physical transformation but also her ability to convey deep emotional complexity.
Critics noted that her portrayal allowed audiences to see Christy Martin, not just an actress playing a boxer. With awards buzz already emerging, many consider this role a potential career-defining moment for Sweeney.
Beyond the physicality, Sweeney highlighted the emotional weight of portraying Martin’s journey, including overcoming domestic abuse and personal struggles outside the ring. She wanted to honor Martin’s resilience and bring attention to her inspiring story, balancing the excitement of the fight scenes with the gravity of her life story.
Christy will be released in theaters on November 7, 2025. Whether audiences are drawn by the intense boxing sequences, Sweeney’s impressive transformation, or the powerful narrative, the film promises a striking depiction of one of the most influential female athletes in boxing history.
With her unwavering dedication, Sydney Sweeney has set a new standard for portraying real-life figures in sports cinema, delivering a performance that is as physically demanding as it is emotionally moving.
