The 29-year-old actress, who teamed up with Johnny Depp and Orlando Bloom for the films, feels it was a great moment in her life, but she would not do it again, reports femalefirst.co.uk.
Asked in an interview, whether she wishes to return to the role of Elizabeth, she said: “No, I don’t think so.
“It was an amazing point in my life, but it was a good five-year chunk. It was incredible, but I can’t really imagine going back to it”.
However, Knightley’s role in the franchise helped her to turn into an A-listed star.
Since then, she has gone on to mix and match her roles, moving from period drama, to indie projects to more blockbuster roles.
