Melanie Griffith on Daughter's '50 Shades' Role: Proud

"Talent, availability, their desire to do it, chemistry with the 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."

"50 Shades of Grey" the movie is expected for release in Aug. 14. Sam Taylor-Johnson has been hired as director for the 50 Shades of Grey film, and Kelly Marcel will create a script.

Soon after that announcement hit the Internet, it was also announced that Charlie Hunnam would be joining opposite Johnson in the lead male role.

"The gorgeous and talented Charlie Hunnam will be Christian Grey in the film adaptation of Fifty Shades of Grey," James added.
