The third royal handmaiden on this list; Australian Rose Byrne has made herself known through supporting parts in such diverse films as "Troy", "Marie Antoinette", "X-Men: First Class" and "The Place Beyond the Pines". Though not quite an A-lister yet, she seems to be an actress on a slow but steady rise. In 2002, Byrne took Keira Knightley's place as Senator Amidala's most trusted servant in "Attack of the Clones".
