Jake Gyllenhaal has gone BEASTMODE for a part in his latest film, Southpaw.

The flick tells the tale of Junior Middleweight Champion Billy “The Great” Hope as he faces a personal tragedy while fighting his way to the top.

Gyllenhaal, clearly went all out to play the part, gaining 15 pounds of muscle for the part of Billy.

“Jake is going to change how people see him,” Fuqua told Deadline of Gyllenhaal’s transformation. “I had him training twice a day in the boxing ring, he did two-a-days seven days a week. I pretty much had him with me and my trainer every day. I took him to almost every fight. I had him train at Floyd Mayweather’s gym in Vegas and we watched Floyd’s fights, and the Manny Pacquiao fight. He trained in New York at Church Gym with real fighters. We literally turned him into a beast,” he added.

Just from the above image I can see this film is going to be sick. Remember Tom Hardy in Warrior, this one has all the makings of something similar, maybe even better…
