Kate Mara goes boldly blond

Goth girl this acting Mara ain't. Try classic California girl.

Unlike her coal-coiffed sister, Rooney, Kate Mara is looking on the sunny side of style, lightening her locks to a shade of citrus and wearing them in beachy waves.

The House of Cards star unveiled her tousled, extra-tawny tresses at today's AFI Awards Luncheon. And unlike either Mara's typical red carpet MO, Kate even almost cracked a smile.
