Rooney Mara has revealed the thing she found most shocking about her extreme makeover for The Girl With The Dragon Tattoo was the change in her eyebrows.
The Social Network star chopped off her long locks, pierced her lip and got covered in temporary tattoos for her role as computer hacker Lisbeth Salander, but it was seeing her newly bleached eyebrows that gave her the biggest jolt.
"I think having my eyebrows done freaked me out the most. That really changed the way I looked," she told the Daily Telegraph.
"I think I was freaked out for about five minutes, then I just let it go and became used to it. The pain wasn't too bad either, with the piercing."
Rooney, 26, said she learned a lot making the movie, which also stars Daniel Craig as journalist Mikael Blomkvist.
"I had prepared myself and I knew how emotionally and physically challenging making The Girl With The Dragon Tattoo would be, but the whole project really pushed me," she admitted.
"The physical challenge was probably even more shocking than the emotional, because there were lots of days that we were doing stunts, with many takes, over and over. It was an amazing experience and I know that I have learnt so much. I am just not quite sure what that is yet."
