In an interview last year with the UK Telegraph, Noomi said that Oplev initially thought she was too good-looking, feminine & soft to portray the sinewy, boyish, hard, punkish Lisbeth. To counter his objections, she went back to him & told him she'd do anything he wanted her to do to become Lisbeth & he finally agreed.
She dieted hard, cut her hair, learnt Thai kick boxing, trained with a fighter, gained her motorbike licence, obtained real body piercings & boy did it show.
Noomi says she hopes to have a career as a European actor, based in Paris or London. However a move to Hollywood isn't on the cards, and she noted that she had no desire to recreate Lisbeth in the Hollywood remake.
Mystic Millie has checked out her infamous crystal ball & predicts a very big future for Noomi. She is one feisty, gutsy chick who'll go far. And by the way, there appears to be no equivalent Swedish word for feisty or gutsy. If Translator is incorrect, do let us know.
