Sydney Sweeney Breaks Down in Tears at Toronto Film Festival Premiere of Christy

Sydney Sweeney was filled with emotion while celebrating the premiere of Christy at the Toronto International Film Festival.

“Christy, you’re absolutely amazing, and I’m so grateful. I’m going to cry! Oh my God, you’re truly inspirational,” Sweeney, 27, expressed on Friday, September 5, as reported by Variety. “Having her alongside me during this journey was a dream come true, but also a bit intimidating because I’m like, ‘Oh my gosh. We’re performing in front of her!’”

She tearfully shared, “I wasn’t entirely sure. I mean, she’s the greatest boxer ever, and here I am trying to do hooks and hits, thinking, ‘Am I doing this right?’”

Sweeney stars as legendary ’90s boxer Christy Martin in the upcoming biopic, and the two women walked the red carpet together on Friday. While 57-year-old Martin looked stunning in a tailored white suit, Sweeney showcased her curves in a custom blush-colored corset gown by Erdem.

During the introduction of their film, Sweeney and Martin displayed a strong connection, with the former pro athlete noting that the Euphoria star underwent a complete transformation for the role.

“She wasn’t the glamorous, beautiful Sydney,” Martin remarked. “She became the tough, gritty Christy.”

Sweeney committed to rigorous training to prepare for the role.

“I trained for two to three months before filming began. I worked with a boxing coach, weight trainers, and nutritionists,” Sweeney explained on Friday. “I was training three times a day, every day, and even while filming, I kept training.”

Beyond mastering boxing techniques and exercising, Sweeney also adjusted her diet.

“Yeah, I consumed a lot of milkshakes and protein shakes,” she joked. “But it was an incredible experience to fully embody such a powerful woman. I felt stronger. It was truly inspiring.”

Sweeney ultimately added 30 pounds through her training regimen.

“I felt incredibly strong and powerful,” she shared with Vanity Fair in a profile published earlier this week. “I loved it. Being able to lose myself in order to become a vessel for someone else is my dream.”

Christy director David Michôd commented that Sweeney was eager to put in the effort to transform into her character.

“She was committed to training, fighting, and transforming herself, and we needed all of that,” Michôd, 52, noted. “One of the aspects that drew me to this story was the potential to create a film that starts as a captivating underdog sports movie but gradually shifts into something that’s deeply moving and profound.”
