Katie Cassidy :is tipped to play hokey inghttp:/enue, Anastasia Steele in the big screen treatment.

It's the literary sensation of the decade, and with the dust settling on the first wave of euphoria surrounding Fifty Shades of Grey... thoughts are turning to the movie adaption.

However, while Katie is looking to be a favourite for the role of Anastasia, others have suggested she might be more suited to play the tenacious Katherine Kavanagh - Ana's best friend and the reason she meets Christian Grey in the first place. 

As well as speculation surrounding the identity of the actress who will play Anastasia, rumours are rife about who will take on the role of Christian Grey.

Names in the fold include Ryan Gosling, believed to be one of the frontrunners for the part, as well as Zac Efron, Magic Mike actor Alex Pettyfer and The Vampire Diaries actor Ian Somerhalder.

Channing Tatum, who also stars in Magic Mike, was also a name linked to the part, but he said in a recent interview that he would only take on the part if his wife Jenna Dewan could play Anastasia.
He said: 'I'd only be allowed if my wife was Ana. She's read the books so I don't think she'd be impressed if she couldn't be Ana!'
