The 2010 fighter/family drama The Fighter ultimately won Bale his first Oscar, thanks to his role as Dicky Ecklund. To play the former fighter turned drug addict, Bale underwent a physical transformation once again. This time, though, he didn't resort to extreme measures, as Collider reported.
"I felt so good and calm with playing Dickie and I was just running like crazy," Bale said. "I could just run for hours on end and I felt really healthy. I don't know. Usually I always say how I do a lot of coke whenever I lose weight. I'm not sure if that's so funny for this movie but there's not a whole lot of secrets to it. But one really good thing is to have this particular water, Aqua Hydrate . . . That helped me to lose weight and I run a lot."
