Fifty Shades of Grey: Who will write the film version?

The "Fifty Shades" story comes in full circle for E.L. James. She was inspired by Stephanie Mayer's Twilight saga; now an established author has publicly announced his intention to write the film version of her book.

On Twitter, author Bret Easton Ellis publicly announced his disappointment over not getting shortlisted for "Fifty Shades."

"It's a very major disappointment to announce that I've somehow been taken off the list of possible screenwriters for Fifty Shades of Grey," he tweets.

E! Online reported Universal and Focus, including producers Michael De Luca and Dana Brunetti, have shortlisted four writers to move forward to film production: Karen Croner (Meryl Streep's One True Thing), Dan Fogelman (Cars, Tangled), Veena Sud (TV's The Killing) and Kelly Marcel (TV's Terra Nova).

Both De Luca and Brunetti shouted out on Twitter that there is no truth to rumours that Emma Watson has been cast for the role. Both producers tweeted separately, saying their first concern is to get a writer and director on board.
