6. Helen Mirren
Helen Mirren's portrayal of Queen Elizabeth II earned her the Best Actress Award that everyone knew she would eventually win. But it is a far cry from some of her other roles. As well as playing her Majesty quite brilliantly, Mirren has played the retired assassin Victoria in RED, Alma Reville the loving wife of Alfred Hitchcock in Hitchcock, the highly-sexed Caesonia in the 1979 romp Caligula and the philosopher and novelist Ayn Rand in The Passion of Ayn Rand. Simply one of the world's greatest actresses.
