Sydney Sweeney has undergone a striking transformation for her latest role, portraying legendary boxer Christy Martin in the upcoming biopic Christy.

Known for her performances in Euphoria and Anyone But You, Sweeney appears almost unrecognisable in the newly released still from the film.

The photo shows Sweeney in a boxing ring, donning gloves and a mouthguard, with a fierce expression as she embodies the former professional fighter. Her appearance is drastically altered, dressed in a white tank top and shorts, her hair dark brown and curly, portraying Martin during the height of her career in the 1990s.

Fans have been vocal in their reactions to the image, with many praising the bold shift in direction. “This transformation is akin to Charlize Theron in Monster,” one viewer commented. Another added, “From lace to leather gloves. Sydney’s switching lanes and I’m here for it.” Others described the change as “a total transformation” and said they “barely recognise her.”

Christy Martin is regarded as a pivotal figure in the history of women’s boxing, credited with bringing widespread attention to the sport during her time in the ring. The film, directed by David Michôd, is set to premiere at the Toronto International Film Festival in early September.

Joining Sweeney in the cast are Merritt Wever, Katy O’Brian, Ben Foster and Ethan Embry. The biopic is expected to focus on Martin’s professional achievements and personal challenges throughout her boxing career.
