Matt Damon – Courage Under Fire

Matt Damon didn't have a personal trainer to lose weight for his role in Courage Under Fire. From his usual 190 pounds, he went down to 139 pounds. On Reddit.com, while answering a fan’s question as to his most challenging role, he named Courage Under Fire, saying, "That is not a natural weight for me and not a happy weight for me even when I was 25. So you know to do that I had to run about 13 miles a day which wasn't even the hard part. The hard part was the diet, all I ate was chicken breast. It's not like I had a chef or anything, I just made it up and did what I thought I had to do. I just made it up and that was incredibly challenging."
