6. She starred in the 2010 remake of A Nightmare On Elm Street.

In the Michael Bay-produced, reimagined, and god-awful, version of the 1984 horror classic A Nightmare on Elm Street, Mara played the film's main protagonist, Nancy Holbrook. This was the first time a global audience got to see the actress in a starring role. While her character was based on the original's Nancy (played by scream queen Heather Langenkamp), also a teen aching to leave town after graduation, Mara described her Nancy as a much lonelier and more anti-social girl than the original's heroine. What she understandably neglected to mention was that her character was also in a lazy, unimaginative cash-grab of a reboot, which we're more than happy to point out.
