Jake Gyllenhaal showed off his fighting skills last night at the Cannes Film Festival. No, the Brokeback Mountain star didn’t get into some boozy brawl along the Croisette—the Weinstein Company screened a sneak peek of his upcoming Oscar buzzy boxing drama, Southpaw. Gyllenhaal, who packed on 15 pounds of ripped muscle for the role as a boxer struggling with addiction in the Antoine Fuqua-directed film, attended the screening aboard a private yacht in a Tom Ford black peak label O’Connor suit with a white dress shirt, black and white tie and black lace up shoes. Festival delegate general Thierry Fremaux introduced the film, calling Gyllenhaal’s performance “incredible and one of his best.” Also starring Rachel McAdams, 50 Cent and Forest Whitaker, Southpaw will be in theaters on July 24.
