Keira Knightley Hot Style Photos: Laurence Olivier Awards 2010 Red Carpet Pictures

Though experienced stage stars Mark Rylance (Best Actor – "Jerusalem") and Samantha Spiro (Best Actress in a Musical or Entertainment – "Hello, Dolly!") both picked up the second Olivier Awards of their careers, the evening was predominantly a triumph of youth over experience. No one epitomized the evening more than 28-year-old American playwright Katori Hall, whose play "The Mountaintop" was the surprise winner of the ceremony, beating the favorite, Jez Butterworth's "Jerusalem," as well as Lucy Prebble's Enron and John Logan's "Red" to win Best New Play.

In other awards, Rachel Weisz won Best Actress for "A Streetcar Named Desire."
