We’re a long way from Euphoria High School now. Sydney Sweeney is stepping into the proverbial biopic ring with her forthcoming portrayal of American boxer Christy Martin, and her transformation is sure to leave you as dazed as a TKO. The actress, who will soon also star alongside Amanda Seyfried in director Paul Feig’s murder mystery The Housemaid, was spotted by paparazzi last fall in character as Martin, wearing a curly brown wig, blue bandana, and a baggy hoodie. As a result, she shared her own photos of herself looking extra buff as the ’90s boxing champion on Instagram, writing,
“[I]’ve been immersed in training to bring to life the story of an incredible woman—a true champion who fought battles both inside and outside the ring. [H]er journey is a testament to resilience, strength, and hope, and I’m honored to step into her shoes to share her powerful story with you all.”
While enjoying a successful career as a boxing champion and pop culture figure, behind the scenes, Martin faced severe abuse at the hands of her then-husband and manager, who eventually made an attempt on her life. When the currently untitled David Michôd film was first announced, the 27-year-old Sweeney described her preparation for the intense role, telling Deadline, “I grappled and did kickboxing from 12-19 years old. 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.”
Here’s everything we know about the film so far:
Who is Christy Martin?
Dubbed the “female Rocky” by the film’s producers, Martin was the most well-known female boxer of the 1990s, appearing on the then-hit sitcom Roseanne, becoming the first woman to sign with promoter Don King, and the only female boxer to be on the cover of Sports Illustrated (the tagline: ‘The Lady Is a Champ’).
Martin, now 56, was born in West Virginia and began her boxing career at the age of 21. A gifted athlete, she quickly rose through the ranks of boxing, putting the sport on the map for women and becoming a cultural figure in her own right.

Despite her professional success, however, she faced greater challenges in her personal life; in 1989, she met her manager, who would later become her husband, James Martin. Christy has described the abuse she suffered from James, who, in 2010, attempted to kill her, shooting and stabbing her several times after an argument at their home. (In 2012, James was found guilty of attempted second-degree murder; he is currently serving a 25-year sentence in a Florida prison.)
Martin is currently enjoying her second act. She’s married to former boxing rival Lisa Holewyne, who she wed in 2017, and is the CEO of Christy Martin Promotions, which sponsors boxing events throughout the Southern United States, where she lives. In 2021, Netflix released a documentary, Untold: Deal with the Devil, about Martin’s life and career, which seems to have inspired the forthcoming biopic.
Director Michôd told Deadline, “I have a history of making movies about damaged men, and I’d been wanting to make a film about a woman with a ferocious energy inside her. When I came across the Christy Martin story two years ago I knew I’d found it. Her ferocity is intelligible and justifiable and audiences will crave it because of the circumstances she was forced to endure.”
Sweeney added, “Christy Martin not only legitimized female boxing, she overcame gender stereotypes, and fought through emotional, physical, and financial abuse. I’m passionate about the fighting world, Christy’s story shines a light on her incredible rise to the top while showing the struggles of fame behind the curtains. I feel compelled to tell a story about a woman who faced so much adversity and didn’t allow it to defeat her. It’s powerful, and emotional.”
How did Sweeney do to prepare?
Speaking to an audience at the Toronto Film Festival premiere of the film, Sweeney said, "I trained for two or three months before I had a boxing coach. I had weight trainers, I had nutritionists, I trained three times a day every day, and then while I was filming, I trained as well."
"And there was a lot of Chick-fil-A," Michôd added. Sweeney noted her diet consisted of "a lot of Smucker's, a lot of milkshakes, a lot of protein shakes," saying, "But it was incredible being able to completely embody such a powerful woman.”
Who else is in the cast?
The cast includes cast of the upcoming biopic includes X-Men actor Ben Foster Martin’x ex James, Merritt Wever (Nurse Jackie), Ethan Embry (Sweet Home Alabama), Jess Gabor (Shameless), Chad L. Coleman (The Wire), Tony Cavalero (The Righteous Gemstones) and Katy O’Brian, who recently starred in another film about female boxers—the sapphic love story thriller Love Lies Bleeding with Kristen Stewart.
Is there a trailer?
The first trailer for Christy dropped September 11, 2025. Soundtracked by Stevie Nicks’s “The Edge of Seventeen,” the clip shows Martin’s origin story as she rises from a soft-spoken aspiring boxer from West Virginia, dressed by her husband in head-to-toe pink, to the powerhouse she later became, championed by a young Don King (Chad L. Coleman). In between, we see how her relationship with her husband deteriorated into one of abuse and control. Watch below:

The film will be released in theaters on November 7, 2025.
