After much speculation on who should play the role of sadist billionaire Christian Grey, do you wonder who should play the role of his older brother, Elliot Grey.

As Universal Studio already hires "The Social Network" team Michael De Luca and Dana Brunetti to work hand-in-hand on the movie adaptation of erotic novel "Fifty Shades of Grey," the casting rumors become stronger.

One of the characters that are pushed aside from the hype is equally good looking older brother of protagonist Christian Grey - Elliot Grey. Elliot is described in the book as Christian's older adopted brother. He is into construction. He is tall, and wide-shouldered with curly-blonde hair and light eyes.

Elliot has a funny, laidback character. He is always teasing his brother for his single status. Elliot is in relationship with Kate Kavanaugh and they have a daughter named Ava Grey.

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.

"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.
