Based on the phenomenal Stieg Larsson bestseller, the haunting murder mystery stars Daniel as a political journalist who teams up with a goth computer hacker (Rooney) to solve a dangerous, decades-old disappearance.

Also starring Christopher Plummer, Stellan Skarsgard, Robin Wright and Joely Richardson, The Girl with the Dragon Tattoo is the first film in a planned big-screen trilogy based on Larsson's bestselling Millennium trilogy, which was already filmed in Sweden in the author's native language.

The Girl with the Dragon Tattoo is coming to theaters December 21.
