50 Shades of Grey movie cast rumors never sleep. It seems like every day another actress and actor are closer to playing Anastasia Steele and Christian Grey in the upcoming 50 Shades of Grey movie adaptation.

During Sunday night's MTV Movie awards Emma Watson rekindled speculation of her playing Ana in 50 Shades during a spoof with comedic actor Jonah Hill. Obviously a hoax, Hill announced he would be playing Christian Grey and Watson would co-star as Steele.

"I'm announcing officially that we'll be starring in the screen adaptation of 50 Shades of Grey," Hill said. "My safety word is tangerine. If I say that word you have to stop doing stuff to me."

All jokes aside, Allison Williams of the HBO hit series Girls is reportedly in the running for the role of Anastasia Steele in the 50 Shadesof Grey movie.

Though Williams has enough of the Disney princess look, with her piercing blue eyes and flowing brown hair, to play Ana, is she seductive enough for serious 50 Shades cast rumors?

Fans of Girls have only seen Allison Williams as Marnie Michaels. Marnie is a whiny, over-privileged socialite living in New York City whose constantly complaining about her lack of direction in life. Though Marnie doesn't quite fit our idea of Ana who seems much more reserved and innocent, it doesn't mean Allison Williams won't. 50 Shades of Grey could be Williams' chance to show she can tap into a softer side of her personality.
