Jake Gyllenhaal [1] lost a ton of weight for Nightcrawler [2], but he's swinging in the totally opposite direction for his next role in Antoine Fuqua's boxing drama, Southpaw [3]. Gyllenhaal allegedly packed on 15 pounds of pure muscle [4] to play Junior Middleweight Champion Billy "The Great" Hope, though it actually looks like a lot more. Honestly, I can't tell if he looks great or terrifying. Sons of Anarchy [5]'s Kurt Sutter wrote the movie, and it'll be released next year. Stay tuned for more details and pictures!
