Unrecognisable is Jake Gyllenhaal in his latest film, Southpaw.
The 33-year-old actor took on the role of Junior Middleweight Champion boxer Billy ‘The Great’ Hope and put on 15 pounds.
Basically Jake turned into a lean, mean, fighting-machine for his latest role.
Director Antoine Fuqua told* Deadline* he's excited for people to see how much Jake has changed and grown into a leading man for the role.
"Jake is going to change how people see him. I had him training twice a day in the boxing ring, seven days a week," said Antoine.
"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… Jake, my god, he's a very electric, powerful fighter in this movie, and a guy who fights for his daughter.
"I'm confident that this will change how people see Jake as a leading man."
We wonder what his ex-Taylor Swift would think?
