Cinching the young British actress's top spot was her co-starring role as Hermione Granger in the six "Harry Potter" films released so far. Fun fact: Watson's overall work actually earned even more in ticket sales than her male Harry Potter chums Daniel Radcliffe and Rupert Grint. (Watson lent her voice to the 2008 animated hit "The Tale of Despereaux.")
Who's the second top-earning actress of the decade? Not Julia Roberts or Reese Witherspoon or Sandra Bullock: it's Dame Maggie Smith, the revered British actress and fellow "Harry Potter" star (Hogwarts teacher Minerva McGonagall).
What about the men? Guinness names Samuel L. Jackson of "Star Wars" and other films, but Entertainment Weekly begs to differ, crowning Orlando Bloom, who commanded $6.5 billion in ticket sales in mega-franchises the "Pirates of the Caribbean" and "The Lord of the Rings."
