Jake Gyllenhaal was recently interviewed by the SAG-AFTRA Foundation for his new movie Stronger. Gyllenhaal’s new movie centers around the inspiring true story of Jeff Bauman, an ordinary man who captured the hearts of his city and the world to become the symbol of hope following the infamous 2013 Boston Marathon bombing. Jake Gyllenhaal stars as Jeff, a 27-year-old, working-class Boston man who was at the marathon to try and win back his ex-girlfriend Erin (Tatiana Maslany).

In the interview, Gyllenhaal talks acting with an amputated leg and how he was able to mimic the movements of the person he was portraying, Jeff Bauman. Check out the full video below.
