I don't think Hollywood would ever have asked her, to be honest. Noomi's comment was in response to a hypothetical 'What if...' put to her by a Swedish journalist recently...
"No, I'm done with her (Lisbeth), and it's up to somebody else to step into her shoes. I don't like to repeat myself. So it's better if someone else does it. I hope they won't take, you know, a big celebrity ... because sometimes the fame makes it difficult to believe in (the character), especially Lisbeth, who is very complicated and dark and so on. So I hope they take someone who is a little less known. Not one of the biggest ones. We'll see."
