Keira Knightley looks real young
Keira Knightley smiles for photographers as she arrives at what is described as "Diana, Princess of Wales' lecture on AIDS" at City Hall in London on December 1, 2003. (Note: The lecture wasn't given by Princess Diana herself, who died in 1997. Rather, it was one in a series of lectures launched by the U.K.'s National AIDS Trust in 1999 in memory of Diana, who had been a patron of the group.)
2003 was the same year that Knightly starred in the hit films Love Actually and Pirates of the Caribbean. She was born in 1985, so she was only 18 when the films were released, and she was likely just 17 when "Pirates," and likely "Love Actually," were filmed. Pretty remarkable.
