Looks like Hollywood has spawned another dramatic beauty make-under.

Just days after Anne Hathaway stepped out with a Sinead O'Connor-esque buzzcut for her role in Les Miserables, Rooney Mara has been spied on the set of her upcoming film The Bitter Pill with a low-key beauty look that's a far cry from Lisbeth Salander.

After sporting piercings, jagged jet-black bangs, bleached brows, and oodles of black liner for The Girl With The Dragon Tattoo, the Oscar nominee is toning it down with brown arches, barely a hint of makeup, and long, ombré hair extensions (possibly a wig?) that go from auburn roots to blond tips. Have we found the missing Olsen triplet?

And forget about those leather biker outfits and kick-butt boots—the actress' new fresh-faced appearance sees her donning a classic camel trench and leather wristwatch.

Then again, considering that Mara plays a woman who becomes addicted to prescription drugs in the thriller, set for a 2013 release, we wouldn't be surprised if the dark-and-gloomy look makes a reappearance.
