Rooney Mara Keeps Androgynous Look

Rooney Mara made her first red carpet appearance since drastically changing her appearance to portray Lisbeth Salander in the U.S. movie adaptation of The Girl With the Dragon Tattoo.

Mara, noticeably thinner, was sporting dark, cropped hair and an eyebrow piercing associated with the hacker heroine. Stellan Skarsgard, who plays Martin Vanger in David Fincher's forthcoming The Girl With the Dragon Tattoo, told E! Online, "Obviously, 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."

Mara was at the premiere of Tanner Hall, an indie coming-of-age flick about an all-girls boarding school in New England cowritten and codirected by Tatiana von Furstenberg and out lesbian Francesca Gregorini, former flame of Portia de Rossi.
