Rooney Mara is famous for her Oscar-nominated performance in The Girl With The Dragon Tattoo.
Starring alongside Daniel Craig, who is currently filming the new James Bond movie Skyfall in London, Rooney, 26, went for an extreme transformation to play Lisbeth Salander.
The petite actress chopped off her light brown wavy locks and dyed them black for her role as the punk computer hacker.
Now, Rooney has changed her 'do again with long brown and blonde dip-dyed hair extensions.
The new look is for her role in A Bitter Pill, which she's currently filming in New York with Jude Law.
