Sydney Sweeney Built a ‘Rocky’ Gym to Prepare for ‘Christy’ as November Release Nears

Early coverage centers on Sweeney’s physical performance.

Overview

  • Sweeney says she constructed a home training setup with a floor ring and heavy bags to mirror Christy Martin’s technique with precision, learning each on-screen fight from archival footage.
  • The biopic moves from its TIFF and London Film Festival screenings into a publicity push ahead of theatrical openings on November 7 in the US and November 28 in the UK.
  • Reviewers consistently commend Sweeney’s transformation and ring work, while several critiques fault the film’s tone and character depth.
  • Social-media debate continues over casting a non-lesbian actor in the role, even as Christy Martin herself promotes the movie and praises Sweeney.
  • Producers and interviews describe a months-long regimen, weight gain of about 30 pounds, and real in-ring impacts to prioritize authenticity in the boxing sequences.
