The 'Fifty Shades Of Grey' producer defended the films casting after backlash from readers.

Dana Brunetti hit back at fans who protested his decision to hire Charlie Hunnam and Dakota Johnson for the lead roles in the big screen adaptation of E.L.James' erotic novel, and insisted producers carefully selected the actors to bring Christian Grey and Anastasia Steele to life.

He wrote on Twitter: ''There is a lot that goes into casting that isn't just looks. Talent, availability, their desire to do it, chemistry with other actor, etc. So if your favorite wasn't cast, then it is most likely due to something on that list. Keep that in mind while hating and keep perspective.'' (sic)

Universal Pictures announced they had chosen 'Pacific Rim' star Hunnam and lesser-known 'Social Network' actress Johnson to star in the movie on Monday (02.09.13), shutting down months of speculation surrounding A-listers tipped to play virginal Anastasia and her S&M-loving billionaire boss.

'The Canyons' writer, Bret Easton Ellis revealed that best-selling author, James had initially wanted Robert Pattinson to play the leading male.

He tweeted: ''Talked to E.L. James at a party over the summer: her first choice for Christian was Rob Pattinson and Matt Bomer was never in the running.''
