Alexis Bledel has a very strong fanbase who want to see her in the role of Anastasia Steele rather than Dakota Johnson, and they’ve even started a petition on Change.org to make it happen. Included in the petition is a plea for the film’s casting director to replace “Sons Of Anarchy” star Charlie Hunnam with Matt Bomer.

The petition currently has over 20,000 signatures and gaining; the petitioner, Barbra Peace, had this to say:

“Matt Bomer is the PERFECT DESCRIPTION OF CHRISTIAN GREY AND ALEXIS BLEDEL IS THE PERFECT ACTRESS TO REPRESENT ANASTASIA STEELE and if THEY ARE NOT, NOBODY WILL BE And I read the whole trilogy and I can assure that Matt is the perfect actor for this movie and Alexis too. So please PLEASE, all of the GREYsessed and Bomerettes in the world NEED those actors. They always will be for us the Christian Grey and Anastasia Steele. WE CAN DO ANYTHING GUYS, ANYTHING.”

Several fans of the books have expressed disappointment in the casting choices, with one person saying that Charlie Hunnam doesn’t bring enough sex appeal.

“Christian is supposed to be sexy and mysterious. Charlie Hunnam looks dirty and very unappealing. I will not be watching the film with this cast. Which is sad because I have waited forever to see this.”

Can't believe there is a petition going about the casting of Fifty Shades – or that 20,000 have bothered to sign http://t.co/tN1oiPECKE
