Having seen Nightcrawler last year, you can witness the commitment that actor Jake Gyllenhaal puts into his projects. He was gaunt, he lost a lot of weight – and it made for a chilling experience as he embodied the role of a desperate man. Now, he’s gone in much of the other direction, gaining weight to play boxer Billy Hope in Antoine Fuqua’s Southpaw.

It’s of great commendation to the actor that he is able to take on two such varied, especially physically, creations – and we had the pleasure of sitting down with him to discuss the transformation he made, and how he went about studying and training for a role unlike any other he’s ever undertaken.

Southpaw is released on July 24th.
