Sydney Sweeney says she told co-star Katy O’Brian “If you break my nose, that’s fine” while rehearsing fight scenes for the Christy Martin biopic, a comment first shared on IndieWire’s social feeds and echoed by O’Brian on Reddit. The actor has trained three-and-a-half months, lifting and kickboxing daily, and added about 30 pounds of muscle to match the six-time world champion’s build.
The film, financed by Black Bear and Anonymous Content, is directed by David Michôd from a script he wrote with Mirrah Foulkes; cameras rolled in North Carolina and wrapped last November. Ben Foster, Merritt Wever, Ethan Embry and O’Brian join Sweeney onscreen, while producers include Kerry Kohansky-Roberts and Sweeney herself. Post-production insiders tell CinemaBlend the team is eyeing a 2026 festival launch while weighing U.S. distributors.
O’Brian confirmed Sweeney took real shots during takes, leaving both performers bruised but satisfying consultants who insisted the bouts look “fight-night” authentic. Sweeney’s willingness, she added, “raised the bar for the entire crew,” even as medics monitored sparring sessions.
Christy Martin, not formally attached to the project, has applauded the casting and hopes the script spotlights domestic-violence awareness along with boxing glory. The Hall-of-Famer survived a 2010 stabbing and shooting by her then-husband and manager, an ordeal she recounts at charity events for groups like Illinois-based WINGS, where she stresses that “survival can be a 50th win.” Advocates say the film could widen conversation around abuse beyond the sports world.
Medical studies show training injuries in boxing are usually less severe than bout trauma, yet repeated sparring still carries notable risk—an edge Sweeney embraced in pursuit of realism. Awards bloggers on OscarRace note that such physical commitment can attract voters but caution that critical reception will hinge on the film’s exploration of Martin’s identity and survival, not on behind-the-scenes bruises. Editors expect to lock picture by early autumn, setting up the true-life comeback story for a crowded awards corridor where authenticity often lands the decisive punch.
