Fifty Shades of Grey casting rumors have been popping up all over the Internet since the movie adaptation was first confirmed last year. With the screenwriter Kelly Marcel selected, and pictures of Universal Studios appearing on author E.L. James' Twitter, the rumors are only heating up.

As of yet, no official casting decisions have been revealed – not even for leads Christian Grey and Anastasia Steele. Top contenders to play the leading man include Ian Somerhalder (Vampire Diaries), Chris Pine (Star Trek), Alexander Skarsgard (True Blood), Matt Bomer (White Collar) and, most recently added to the list, Man of Steel star Henry Cavill. Meanwhile, Lucy Hale (Pretty Little Liars), Ashley Greene (Twilight), Nina Dobrev (Vampire Diaries), Alexis Bledel (Gilmore Girls) and Emilia Clarke (Game of Thrones) have all been suggested to fill the role of Ana.

In April, Bomer’s Magic Mike costar Alex Pettyfer, starred as Christian Grey in a sample scene directed by Gus Van Sant. The filmmaker shot the sex scene with Pettyfer and an unnamed actress to send to producers in an effort to get the job directing the Fifty Shades of Grey movie. The unsolicited sample depicted Anastasia Steele losing her virginity to Grey. Insiders say that Van Sant and Pettyfer have the inside track at the moment.

Until official decisions are announced, it can be expected that fans of the "mommy porn" trilogy will continue to suggest actors to play the couple in the “love story with a kink.”

The Fifty Shades of Grey movie is expected to hit theaters summer 2014.
