Sydney Sweeney is stepping into the ring—literally and figuratively—as she transforms for her latest role in the upcoming biopic Christy. The 27-year-old Euphoria star unveiled the first glimpse of her dramatic portrayal of legendary boxer Christy Martin on Instagram, revealing not only her physical transformation but also the intensity of the role.
On July 22, Sweeney shared a behind-the-scenes still from the film, writing, “CHRISTY premiering @tiff_net,” confirming its debut at the prestigious Toronto International Film Festival. The photo showcased her powerful new look, for which she reportedly gained 30 pounds to accurately depict the boxing icon.

Fans were quick to flood social media with praise and anticipation, many calling the role a potential career-defining moment for the Immaculate and Madame Web actress. One admirer commented, “Future Oscar winner,” while another wrote, “Sydney Sweeney is about to blow everyone away with this performance.”
Set for release in September 2025, Christy tells the harrowing yet inspiring true story of Christy Martin—one of the most prominent female boxers in the 1990s and early 2000s. The film delves into her rise in the male-dominated sport and the traumatic events of 2010 when she survived a violent attack by her then-husband and trainer, James Martin.
Joining Sweeney in the film is Ben Foster, who plays James Martin. The biopic is directed by acclaimed filmmaker David Michôd, known for The King and Animal Kingdom.
With its gripping real-life narrative and Sweeney’s dedication to the role, Christy is already generating Oscar buzz ahead of its TIFF premiere. As audiences await its full release, Sweeney’s transformation is proving she’s not just ready to take on the gloves—she’s aiming for gold.
