Anne Hathaway
In order to get into the mind of Fantine, a character in Les Miserables that was dying of tuberculosis, Hathaway lost 25 pounds. She put herself on a 500 calorie a day diet for a month before Les Mis began filming, which took a serious physical and emotional toll on her.
Was It Worth the Pain?
Although Hathaway does not regret going out of her way to accurately depict this character, she does not recommend that anyone does this to their body. “I was in such a state of deprivation—physical and emotional," stated Hathaway. It took her months to return to her usual self after the filming of Les Mis.
