Worked hard to play Monroe: Michelle Williams

London: Michelle Williams says she had to work hard to play Marilyn Monroe in "My Week With Marilyn" and that she needed a long time to prepare for the physical changes the part needed.

"Unfortunately, it (weight) went right to my face. So at some point it became a question of, `Do I want my face to look like Marilyn Monroe`s or my hips?` It felt like being reborn," femalefirst.co.uk quoted the 32-year-old as sying. "It felt like breaking my body and remaking it in her image, learning how she walked and talked and held her head. None of that existed in my physical memory, and I knew I needed as much time as possible to make it part of me." To prepare for the role, Michelle spent six months researching on Marilyn by studying her old movies and photographs, reading biographies, diaries, and old letters and tracking down old clips on YouTube. "I`d go to bed every night with a stack of books next to me. And I`d fall asleep to movies of her. It was like when you were a kid and you`d put a book under your pillow hoping you`d get it by osmosis," she added in an interview with US` Vogue magazine. IANS
