Cast as Fantine in the upcoming big-screen adaption of "Les Miserables," the actress wanted to bring authenticity to her role as a dying prostitute, and it seems she was successful as she appears very gaunt in the trailer.
Going into "Les Mis," Hathaway was already in tip-top shape. She was coming off of her role in "The Dark Knight Rises," for which she spent 10 months doing hardcore weight training and martial arts, and even adopted a vegan diet.
"I had to be obsessive about it -- the idea was to look near death," Hathaway tells the magazine. "Looking back on the whole experience -- and I don't judge it in any way -- it was definitely a little nuts. It was definitely a break with reality, but I think that's who Fantine is anyway."
Hathaway, who turns 30 this week, says she exerted herself so much in the role, which is already generating Oscar buzz for the actress, that she had difficulties transitioning back into her everyday life once filming wrapped, and had to lean heavily on her beau, actor-turned-jewelry designer Adam Shulman, whom she married on September 29.
Calling Shulman her "true love -- the full-on romantic, till-death-do-us-part real deal," Hathaway says that their Big Sur, California, wedding was "a blast" and their friends "stayed and partied and danced till really late."
As for that Valentino gown, which was custom made by the retired designer, she said a lot of back and forth went into its creation. "I begged him during the first fitting to make the train detachable," Hathaway shares. "He looked at me and said, 'But it is a dress, not a costume.' The memory of creating it with him is something that I will treasure forever. He somehow read my mind and designed the dress that I'd always wanted."
Something else she always wanted -- and just didn't know it! -- is her new no fuss haircut.
While she may be happy with less when it comes to her appearance, she's looking forward to building a family with Shulman. "I want to be a mother, and I anticipate loving my children quite fiercely," she says. "I think about it all the time, though it's a silly thing to think about because the kind of mother I'll be depends on the kind of children I have. I can't wait to meet them."
