When The Dark Knight Rises (finally!) hits theaters on July 20, it is fair to say that all eyes will be on Anne Hathaway as Catwoman and, in more ways that one, how well she fits into Selina Kyle's tight-fitting catsuit. Hathaway, who pursued the role in Christopher Nolan's final installment in the Batman trilogy, recently admitted that she made some hefty sacrifices to become the iconic, feline femme fatale.

"It was a psychological terrorist," Hathaway told Allure. "The suit, thoughts of my suit, changing my life so I would fit into that suit. … It dominated my year. … I didn't understand how you could be thin and strong. I went into the gym for ten months and didn't come out."

These days, Hathaway is no stranger to extreme dieting and exercise for a movie role. To play Fantine in Tom Hooper's reboot of Les Misérables, she has had to become even thinner. "I'm doing some crazy weight stuff right now," she said. "I'm on day six of detox … this diet makes me break out, so I love that. Nothing like living on hummus and radishes and then be all, 'And I got a pimple. Yeah!'"
