Just, who will play, Christian Grey?

Whilst it's not really my cup of tea, and admittedly I have read not even one of the trilogy, there is no denying that erotic series Fifty Shades Of Grey has taken the world by storm this summer, outselling legendary Harry Potter book sales (much to my dismay).

But now the hype around the novels has died down, everyone is discussing the prospect of a film adaptation. It has been confirmed that there will be one, but who will play each character is very much under the scrutiny of fans everywhere.
