The drastic change is all part of Mara's next role as the anti-establishment, chain-smoking private investigator in the movie adaption of Stieg Larsson's Girl With the Dragon Tattoo.

She and Daniel Craig, who plays Mikael Blomkvist, have been filming David Fincher's American version in Sweden. The movie has a December 2011 release.
