Sydney Sweeney has traded lip gloss and lace for blood, bruises, and boxing gloves—and no, this is not an Euphoria plot twist. The actress is starring in Christy, a biopic about the legendary boxer Christy Martin, and it’s easily her most intense, most physically unrecognisable role yet. The “coquette-core” era? Consider it retired.
The first images just dropped, and let’s be clear—this isn’t your average “serious role” glow-down. Sydney transformed. Like, “are we sure that’s the same person who seduced Glen Powell while sipping tequila on a boat?” levels of transformed. One fan even said it was giving Charlize Theron in Monster—and honestly, not wrong.

In Christy, she plays the trailblazing female boxer who broke into a violently male-dominated sport, got famous fighting on a Tyson undercard (iconic), and survived actual attempted murder by her husband-slash-trainer. It’s not a biopic. It’s a full-body exorcism of Sydney’s rom-com comfort zone. And it already smells like awards bait.
Directed by David Michôd, co-written with Mirrah Foulkes, and with Christy Martin herself involved (because authenticity matters when you’ve literally survived everything), the film doesn’t shy away from the mess—addiction, trauma, identity crisis, and violence both in and out of the ring. And Sydney? She’s not playing around.
She trained for months. Built muscle. Lost her size 23 waist. Gained thighs that probably fear no man. In her own words to W Magazine:
“I didn’t fit in any of my clothes… My boobs got bigger. And my butt got huge. I was like, Oh my god. But it was amazing: I was so strong, like crazy strong.”
Forget the glam squads and custom corsets. This time, Sydney’s power is protein shakes and pain.
The film premieres at TIFF in September 2025 (yes, start prepping your Oscars predictions), and while the global release date is still TBD, the hype has already laced its gloves and stepped into the ring.
If Christy lands the way it’s shaping up to, this could be the role that officially takes Sydney from hot-girl-next-door to “she’s got range” territory. Because behind all the sweat and broken ribs? A story about survival, legacy, and reclaiming power—mess and all.
