Sydney Sweeney is stepping into the boxing ring for what might be her most physically and emotionally demanding role yet in Christy, the new biopic that premiered at TIFF, where the Emmy-nominated actress portrays legendary boxer Christy Martin. Sweeney committed fully to the role, literally delivering real punches alongside her co-stars: “Every single fight you see, we are actually punching each other; we are going full force,” she told Vanity Fair — and yes, she emerged with bruises and concussions to prove it.
The actress is also making her case beyond the ring: “I was blown away that her story wasn’t more known on a universal level,” Sweeney said of Martin, calling her “one of the most harrowing and inspiring women that I’ve ever met in my entire life.” That emotional weight is underscored by Sweeney’s physical transformation, training for months and gaining more than 30 pounds, stepping into Martin’s shoes.
