Just like her character in The Duchess, actress Keira Knightley also has to deal with press intrusion into her private life.

Knightley said she doesn't particularly like the press: "If you're nice I like you."

"No actor particularly likes talking about their private life. I think partly it ruins the magic of the film.

"People that go and see it should get completely lost and believe that these people are real and I don't think it helps to know the background of the people."
