Jake Gyllenhaal doesn't only posses some serious acting skillz…
His body transformation abilities are off the charts!
Sure, many actors before him have changed their bodies in huge ways for a role, but this time seems different. Jake is insanely ripped and he's acting his heart out! There's proof in the official trailer for his new movie Southpaw (above)!
The film was written by Sons Of Anarchy creator Kurt Sutter and is going to be directed by Antoine Fuqua, who also directed Training Day!
