The film is already in the works. The British author E.L. James handpicked the producers of the successful Facebook movie "The Social Network" to work on the production. The two will now begin the very important task of casting the feeble heroine Anastacia Steele and charismatic billionaire Christian Grey.

There is no word yet about the official casting in the movie adaptation. However, "Vampire Diaries" Ian Somerhalder and Felicity Jones topped different casting polls and will most likely bag the roles of Christian Grey and Anastacia Steele, respectively.

The author of the mummy porn trilogy was firm that Twilight's sweetheart Kristen Stewart and Robert Pattinson will not be casted in the film adaptation.

"Fifty Shades of Grey" is an erotic novel that started as Twilight fan fiction. The characters of Edward Cullen and Isabella Swan served as an inspiration for the characters of Christian Grey and Anastacia Steele.

However, James pulled her work from the fan fiction page due to its popularity as well as the sexual nature of her work. She then developed a trilogy. The first book was followed by "Fifty Shades Darker" and "Fifty Shades Freed."

After publishing her work, the novel now passed the 20 million mark and has a growing fan base. Moreover, a lot of people are interested on who will complete the cast for this controversial project.
