The actress’ personal style completely transformed during the 14 months she spent portraying tattooed and pierced gothic computer hacker Lisbeth Salander for the film and is no longer very feminine, lacy, pink, whimsical and romantic.
She said: “My wardrobe has completely changed. It had to, partly because of my hair and partly because I stopped feeling comfortable in what I used to wear.
“I don’t feel comfy in those clothes anymore because I have been living as Lisbeth for 14 months.”
For the role Rooney also had to get her nipple pierced – which she has since kept in – and had to shave her head, which she said she was “really happy” to do.
Rooney also won her role in ‘The Girl with the Dragon Tattoo’ for her wiliness to completely transform herself, with director David Fincher explaining: “She was willing to risk everything. Her take on Lisbeth was as someone who can turn it completely off.”
