Girl with the Dragon Tattoo?
Could she play Lisbeth Salander? I've been seeing a lot of "usual suspects" casting ideas for Fincher's remake, and I wonder if AJ couldn't be a more outside-the-box idea for the role. She's got the chops, and I think a less well-known actress could bring a little more mystery to the proceedings - which (along with Fincher, Craig, et al) could help win over sceptical fans of the original.
"So, what am I doing? Oh, I'm chasing this guy. (gunshot) No, he's chasing me."
