The Prince Of Persia has certainly come down a few pounds! Jake Gyllenhaal has undergone a dramatic weight loss for his new role in the 2014 film Nightcrawler. The movie, also starring Big Love's Bill Paxton and Renee Russo, is about a young man who stumbles upon the underground world of Los Angeles' freelance crime journalism. Gyllenhaal told Us Weekly of his character Lou, a freelance reporter, "I knew that [Lou] was literally and figuratively hungry." That being said, the actor revealed he went into a mode where he too was "always a bit hungry."
