Keira Knightley began her acting career, aged only seven years old, when she appeared in an episode of BBC TV programme Screen One.
The storyline of episode 'Royal Celebration' revolved around Charles and Diana's wedding (ooh, topical… sort of). Footage of her appearance was dug up when she was a guest on The Jonathan Ross Show, and she's virtually unrecognisable as the starlet we know today.
Glamour rating? Thankfully low, as she rocks a look suitable for her age: baggy green T-shirt and scruffy hair.
