Hollywood actress Sydney Sweeney takes on the challenging role of former professional boxer Christy Martin in the highly anticipated biopic *Christy*. Directed and co-written by David Michôd, the film delves into two decades of Martin’s life, capturing her rise from an accidental entrant into boxing to becoming one of the most celebrated female fighters of the 1990s. The movie, which premiered at the London Film Festival, also explores her tumultuous relationship with her coach-turned-husband Jim Martin, portrayed by Ben Foster, and the harrowing consequences of his control over her career and personal life. Martin, now 57, was the first woman to sign with boxing promoter Don King and competed from 1989 to 2012. Beyond her boxing achievements, the film highlights her advocacy work through her non-profit *Christy’s Champs*, which supports family abuse victims. Sweeney, known for her roles in *Euphoria* and *Anyone But You*, underwent a rigorous three-month transformation for the role, gaining 35 pounds and training intensively with boxing coaches, weight trainers, and nutritionists. She described the experience as physically demanding but empowering, even sustaining a concussion during filming. The movie, set for a global release on November 7, not only celebrates Martin’s boxing legacy but also addresses critical themes of domestic violence and sexual identity. ‘We set out to make a film that’s about many things, not just boxing,’ said co-writer Mirrah Foulkes. Michôd added, ‘I wanted to understand how coercive-control relationships function, because they are tragically common worldwide.’
