Where You've Seen Her: Unless you're from the land of tea and crumpets, you probably don't know much about this British beauty, but she's actually been in the limelight for years. Getting her start in 2005 with the TV mini-series Fingersmith, Michelle had various TV cameos - Waking the Dead, Cranford, The Hollow Crown - before landing her first big-screen role in Hanna. But it was her 2010 break-through role in Downton Abbey that really brought her into the public eye. Catch the show's fourth season premiere this Sunday on BBC America (said with a terrible British accent and upward pinky).
