Kristen Stewart Talks ‘Fifty Shades of Grey,’ Will She Star in the Movie?

As fans of the Twilight series know, Fifty Shades of Grey was initially written as graphic fan fiction inspired by that series. Now with talks that the erotic novel is being made into a movie, EW caught up with Kristen Stewart to see if she and her on-and off-screen beau Robert Pattinson had heard about the racy book — and if they’d be up for taking on the leading roles.

“It’s funny — I heard about it yesterday. Rob [Pattinson] and Wyck [Godrey], our producer, were talking about it. I’ve heard it’s quite sexy, very titillating,” K-Stew said.

Will she read it?

“Hell, yeah!” Kristen said.

Fifty Shades focuses on a 21-year-old college student, Anastasia Steele, who starts a relationship with wealthy entrepreneur, Christian Grey, who leads her into an S&M deal.

The story started as a Twilight fan fiction. Despite the lack of sparkly vampires, Ana is said to be a re-imagined Bella, while her man Christian Grey is a revamped Edward.
