Famous for: Nearly stealing the spotlight from Sienna Miller in Casanova
Reading-born Natalie was fresh out of the Webber Douglas Academy of Dramatic Art when she was picked by director Lasse Hallstrom to star as Victoria alongside Heath Ledger in 2005 flick Casanova. The movie gave fledgling actress the chance to not only to showcase her comic timing but also her swordsmanship - she's a talented fencer. Two years later she was in a corset again, this time to play Anne Boleyn opposite Jonathan Rhys Meyers in a lavish American TV production about Henry VIII entitled The Tudors. The actress, who's also a mezzo soprano singer, has appeared in various UK theatre productions and made guest appearances in TV series such as Rebus and Distant Shores.The blonde beauty is also known for starring as Margaery Tyrell in the HBO series Game of Thrones.
