We have seen Charlize Theron transform for a bunch of roles, but things were a little different when she had to gain 50 pounds for ‘Tully’. Theron admits that losing all that weight afterwards was more difficult this time around: “Being 42 and trying to lose it, was a little different too. I definitely thought for one second I was dying because nothing was happening. My doctor was like: ‘Yeah, you’re 42. Take it easy!”
