Jake Gyllenhaal lost a ton of weight for Nightcrawler, but he's swinging in the totally opposite direction for his next role in Antoine Fuqua's boxing drama, Southpaw. Gyllenhaal allegedly packed on 15 pounds of pure muscle 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's Kurt Sutter wrote the movie, and it'll be released next year. Stay tuned for more details and pictures!
