Producer Dana Brunetti took to Twitter to explain the process for choosing the actors who will play lovers Christian Grey and Anastasia Steele.
"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," Dana tweeted.
"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."
Hate tweets
Some hardcore fans of the steamy novels have been quick to share their disappointment - and even anger - over the casting of 33-year-old Charlie, a British actor best known for his role as a bad boy biker in the hit TV series Sons of Anarchy and as the lead as a robot-fighter in Pacific Rim, as billionaire masochist Christian Grey.
Dana found himself the target of hate tweets and death threats from incensed fans, and retweeted some of the more choice responses to the casting news, but he continued to defend his choice, posting sexy photographs of Charlie on Twitter and Facebook.
He even took the opportunity to poke fun at Donald Trump:
OK Donald, who did YOU want to play Christian and Anastasia? "@realDonaldTrump: Our country is looking very bad right now!"

Perhaps exhauted by the constant stream of negative responses to the news, Dana tried to put the issue to bed once and for all:
There can only be one... and it is done.

Author E.L. James, who also acts as a producer on the movie, also sent her fans a message following the casting news she revealed.
Fans seemed more forgiving about the casting of newcomer Dakota in the role of wide-eyed student Anastasia. The 23-year-old daughter of Melanie Griffith and Don Johnson had a small role in The Social Network and 21 Jump Street, opposite Channing Tatum.To all the supporters, lovers and haters - thank you so much for the passion that you have for this project. You all rock. All of you. ?
