Sydney Sweeney is unrecognizable. Seriously. If you walked past her on the street in her full "Coal Miner’s Daughter" getup, you’d probably just think she was a tough-as-nails local from a 1990s West Virginia town. She traded the glam for a brunette mullet, brown contacts, and 30 pounds of raw muscle.
The movie, simply titled Christy, isn't just another sports flick where the underdog wins a trophy and everyone goes home happy. It’s heavy. It’s brutal. Honestly, it’s kinda terrifying at points.
Why the Sydney Sweeney Christy Martin movie is more than a boxing story
Most people hear "boxing biopic" and think of Rocky. They expect training montages and a big final fight at the MGM Grand. While Christy has those things—and the montages are actually pretty intense—the real heart of the film is a survival horror story happening inside a house in Florida.
Christy Martin didn't just fight women in the ring. She spent twenty years fighting her trainer and husband, James "Jim" Martin. He’s played by Ben Foster, who is straight-up chilling in this role. He managed her, coached her, and then systematically dismantled her life behind closed doors.
The physical transformation was no joke
Sydney didn't just wear a padded suit. She went through a three-month training camp that would make most professional athletes sweat. We’re talking:

She basically lived on protein shakes and PB&Js to bulk up her frame. She told Variety she was "getting pummeled" during filming. There were no stunt doubles for the big hits. When you see her get a black eye on screen, it wasn't always just makeup. She wanted the "savagery" to feel real.
What really happened with the 2010 attack?
This is the part of the sydney sweeney christy martin movie that most viewers find hard to watch, but it’s the most important piece of the puzzle. In 2010, Christy finally told Jim she was leaving him. She had reconnected with her high school girlfriend, Sherry Lusk.
Jim didn't just argue. He snapped.
He stabbed her multiple times and shot her in the chest with her own pink handgun. He left her for dead and went to take a shower. That’s the level of coldness we’re dealing with. But Christy is a fighter in the most literal sense. She crawled out of that house, flagged down a stranger, and survived.

The movie doesn't shy away from this. Director David Michôd (who did Animal Kingdom) makes the third act feel like a visceral, heart-pounding escape. It’s not "inspiring" in a Hallmark way; it’s inspiring in a "how did a human being actually survive that?" way.
Breaking the "perfect athlete" myth
One thing the film gets right—that a lot of biopics miss—is that Christy wasn't a perfect victim or a perfect hero. The movie shows the mess. It shows the drug use, specifically a codependent cocaine addiction she shared with Jim. It shows the internal homophobia she struggled with, even publicly mocking lesbian opponents like Lisa Holewyne (played by Katy O'Brian) while being a closeted lesbian herself.
It’s complicated. Life is messy like that.
The supporting cast is stacked
While Sydney is the engine, the people around her bring the 90s boxing world to life:

- Ben Foster as Jim Martin: He’s so good at being bad that the real Christy Martin said her family couldn't even stand to be near him on set.
- Katy O’Brian as Lisa Holewyne: She plays Christy’s rival-turned-wife. Their chemistry is the emotional anchor that keeps the movie from being too dark to handle.
- Chad L. Coleman as Don King: He nails the eccentric, high-energy promoter vibe without turning him into a cartoon.
- Merritt Wever: She plays Christy’s mother, Joyce, who has a heartbreakingly realistic reaction to the abuse—mostly denial and misplaced blame.
Why this movie matters in 2026
We’re in an era where "strong female leads" are everywhere, but Christy shows a different kind of strength. It’s not about being invincible. It’s about being broken into a million pieces and having the sheer, stubborn will to put yourself back together.
The real Christy Martin is still around. She’s an activist now. She runs a nonprofit called Christy’s Champs. She actually spent a ton of time with Sydney during production, making sure the boxing stayed authentic and the emotional beats hit where they needed to.
Misconceptions about the ending
People think the movie ends with her retiring. It doesn't.
The most powerful moment isn't a knockout. It’s when Christy walks back into her gym for the first time after being shot and stabbed. Her team is there. Jim is gone. She’s still standing. That scene apparently made the real Christy cry when she watched the screening at TIFF.
Actionable Insights for Viewers and Athletes
If you're watching this for the sports history or because you're a fan of Sydney Sweeney, here’s how to get the most out of the experience:
- Read the Memoir: If the movie leaves you wanting more detail, pick up Fighting for Survival by Christy Martin. It fills in the gaps about the court case and her life after boxing.
- Watch the Documentary: Netflix has a doc called Untold: Deal with the Devil. It features the real footage of the 1996 fights and interviews with the actual people involved.
- Recognize the Signs: The film is a textbook study in domestic coercive control. If someone you know is in a situation where a partner controls their finances, phone, and career, that's the "Jim Martin" red flag.
- Follow the Career: Keep an eye on Katy O'Brian and Sydney Sweeney during the 2026 awards season. Their performances here are widely considered career-bests that move them far beyond their previous roles.
