Brunette Rooney is currently promoting her much-anticipated film The Girl with the Dragon Tattoo, which hits theaters Dec. 21, while auburn-haired Kate has created buzz with her role in the popular FX show American Horror Story.
Rooney, 26 and Kate, 28, were photographed Tuesday at the afterparty for the New York Premiere of Dragon Tattoo. Rooney, dressed in black, has just a tinge left of the extreme makeover she underwent to play the role of wiry, moody hacker Lisbeth Salander.
Kate went with a brighter look, and sparkled in a pink dress as she showed up to support her younger sister on her big night.
Rooney has a lot to celebrate this season: The movie is getting Oscar buzz and her role has so far nabbed her a Golden Globes best-actress nod.
The well-known pair have famous parentage, too: Family on their mother's side founded the Pittsburgh Steelers football team, and their father's side of the family founded the New York Giants.
