Rooney‘s Girl with a Dragon Tattoo cast mate, Stellan Skarsgard, recently told E! Online that she’s “doing a great job.”

“Obviously, [director David] Fincher wanted to go with someone even younger than the Swedish version. He wanted someone more vulnerable, more androgynous and I think it pays off,” he shared.

FYI: Kate is wearing a dress, clutch, and sandals all by Prada. Rooney wore Brian Atwood‘s nude patent leather “Drama” pumps.
