Martin, 57, is widely credited for bringing female boxing into the mainstream.<\/p>\n In an interview with\u00a0W Magazine<\/a>\u00a0published June 9, Sweeney opened up about the transformation required for the biopic. The actress gained over 30 pounds and trained more than three months to recreate Martin’s toned physique, she told the outlet.<\/p>\n “I started eating. I weight-trained in the morning for an hour, kickboxed midday for about two hours, and then weight-trained again at night for an hour,” Sweeney said. “My body was completely different. But it was amazing: I was so strong, like crazy strong.”<\/p>\n The premiere comes on the heels of her recent film Americana<\/a>, which was released in theaters on Aug. 22. The film is set in a South Dakota town as everyone gets embroiled in a plot to steal a prized Lakota “ghost shirt.”<\/p>\n The film releases also come shortly after her American Eagle advertisement left her\u00a0embroiled in\u00a0controversy<\/a>\u00a0in July, due in part to its tagline, “Sydney Sweeney Has Great Jeans.\u201d Critics of the ad claimed that using the word “jeans” as a play on “genes” was racially charged and hinted at genetic superiority.<\/p>\n Ahead of her TIFF premiere, Sweeney told Vanity Fair<\/a> that she would not address any questions related to her American Eagle campaign<\/a> while in Toronto \u2014 she was there to support her film.<\/p>\n “I am there to support my movie and the people involved in making it, and I\u2019m not there to talk about jeans,\u201d Sweeney said in the interview published Sept. 4. \u201cThe movie\u2019s about Christy, and that\u2019s what I\u2019ll be there to talk about.\u201d<\/p>\n Steve Granitz\/FilmMagic<\/p>\n Sydney Sweeney at ‘Americana’ screening<\/p>\n Never miss a story \u2014 sign up for\u00a0PEOPLE’s free daily newsletter<\/a>\u00a0to stay up-to-date on the best of what PEOPLE has to offer\u200b\u200b, from celebrity news to compelling human-interest stories.<\/p>\n On Tuesday, Sept. 2, sources confirmed to PEOPLE that the actress and\u00a0Scooter Braun<\/a>\u00a0are “casually hooking up.”<\/p>\n “Everything is casual.
