British actress KEIRA KNIGHTLEY struck up a close friendship with her PRIDE AND PREJUDICE 'sisters' - it was one of the few films where she worked with women her own age.

The Pirates Of The Caribbean beauty is accustomed to appearing with older co-stars and relished the opportunity to make young female friends on the set of the JANE AUSTEN adaptation.

And Knightley, who played feisty ELIZABETH BENNET, admits she misses her on-screen sisters, Bond girl Rosamund Pike and Carey Mulligan, who played JANE and KITTY in the box office hit.

She says, "They've both become good friends of mine now and we talk all the time.

"For the first time in my life I worked with women of my own age, and we were all at the same life stage and had the same interests.

"I rarely meet people my age at work, so it was really lovely."
