No 'Fifty Shades of Grey' for Keira Knightley

London: Actress Keira Knightley is adamant she won't be playing Anastasia Steele in the movie adaptation of erotic novel 'Fifty Shades of Grey'. The 27-year-old says she will 'definitely' not be starring in the anticipated adaptation of E.L. James' erotic novel, which details a story about billionaire Christian Grey's relationship with young student Anastasia Steele, reports contactmusic.com.

Asked whether her next film project would be a more risque literary adaptation than she has done in the past, Keira insisted: "No, it's not. It's not going to be 'Fifty Shades of Grey'. You know, I normally don't like to give a definite about anything, (but) I can definitely say it will not be 'Fifty Shades of Grey'."
