Her first high profile role came in 1999, when she played the part of Sabe, the decoy queen in Star Wars Episode I. Her part in the film was kept secret in the lead up to the much anticipated release, and Natalie Portman was promoted as having played the roles of both the real and decoy queens so as not to spoil the surprise. A lot of fans still think Portman played both roles.

Keira Knightley has reportedly banned studio bosses from digitally enhancing her cleavage.

The 23-year-old actress - who plays Georgiana, the Duchess of Devonshire, in period drama 'The Duchess' - is "proud" of her modest assets and didn't want them changed in any publicity shots.

Keira Knightley has denied her character in 'The Duchess' reflects Princess Diana. The actress - who plays Georgiana Spencer, Duchess of Devonshire in the 18th century period drama - has blasted a trailer for her latest film, which compares her character to the late royal. Spencer was a distant relation of Diana, but the film makes no reference to her.
