Long before Rooney Mara landed major roles in films like "The Girl With the Dragon Tattoo," she was taking gigs as an extra on her older sister, Kate's movies. These days, however, the sisters' stars are both shining bright, with Kate, 30, starring in the critically acclaimed Netflix show, "House of Cards," and Rooney, 28, having already snagged her first Oscar nomination. In the new issue of Elle, Kate opens up about what it's like to see a little sister following in her big sister's footsteps land the first nod from the Academy. It's becoming a common question, Kate tells the magazine. "People want it to be much more complicated than it is. Family is family, a career is a career," she says. "We both plan on acting for a really long time. We have different paths. Plus, we're both more concerned with beating ourselves up than competing with each other."
