Although she’s a modern-day s-- symbol in Hollywood, Sweeney transformed her body during filming, gaining a staggering 30 pounds to portray the character.

Sydney Sweeney produced the biopic through her production company, Fifty-Fifty Films.

Despite previously taking on less taxing roles where she didn’t have to rigorously work to transform her body, Sweeney shared how playing the role of a professional boxer was actually in her wheelhouse.

“I grappled and did kickboxing from 12-19 years old,” she told another news outlet. “I’ve been itching to get back into the ring, train, and transform my body. Christy’s story isn’t a light one. It’s physically and emotionally demanding. There’s a lot of weight to carry. But I love challenging myself.”
