Keira Knightley won't go back to Pirates of the Caribbean

Los Angeles  - Keira Knightley won't return to Pirates of the Caribbean.

The 29-year-old actress played the role of Elizabeth Swann in the first three films in the franchise, Pirates of the Caribbean: The Curse of the Black Pearl, Pirates of the Caribbean: Dead Man's Chest and Pirates of the Caribbean: At World's End, but she's confirmed she has no interest in returning in any future installments.

Quizzed about the series - which is based on the theme park ride of the same name - Knightley told BBC Radio 2's 'Steve Wright in the Afternoon': "I have no idea, I don't know what they're doing. My time has definitely passed, I loved it, it was an amazing experience but I won't be going back."

Since her and her on-screen love interest Orlando Bloom's departure in 2007, Johnny Depp, Geoffrey Rush and Kevin McNally have returned for 2011's Pirates of the Caribbean: On Stranger Tides - which also starred Penelope Cruz - and are in the process of making the fifth installment Pirates of the Caribbean: Dead Men Tell No Tales, and Knightley thinks the franchise could continue forever.

She added: "I don't know what they're doing, there are so many piratical tales they could tell, it's a fun franchise, it was a lot of fun."
