LATEST: Keira Knightley only realised there was a connection between her new movie THE DUCHESS and DIANA, PRINCESS OF WALES after the film was criticised for using footage of the late royal in a promo.
In the new film, Knightley plays Georgiana, Duchess of Devonshire, a distant relation of Diana - who died in a car crash in Paris in 1997.
Bosses behind the picture have come under fire for using shots of the late Princess in a trailer for the film and emphasising the link between the lead character and her modern-day descendant.
But Knightley insists she didn't know anything about the Diana connection when making the movie - and admits she doesn't even know that much about the late royal because she was so young when she died.
She says, "I was only 11 when Diana died, so I don't really know much about her story. It didn't even occur to me to portray Georgiana as Diana, as I wasn't conscious of the similarities, and nobody suggested I should. I was always Georgiana, never Diana."
