The highly anticipated film adaptation for E.L. James S&M novel, "Fifty Shades of Grey" is said to hit theatres by summer of 2014. With casting still far off, here are ten good reasons for Universal Studios to take in "Twilight" star, Kristen Stewart as Anastasia Steele.

Kristen Stewart would unlikely pass as an inexperienced woman when it comes to sex. As proven by the threesome in "On the Road", Kristen can definitely do a sexy scene and a full on nude one as well. Obviously, Stewart would have no problem playing the role of the 22-year old college student, Anastasia Steele who had gotten into a contract with 27-year old entrepreneur, Christian Grey.

While some "Twilight" fans may disagree with the casting, Stewart is the best choice to play Anastasia Steele. Kristen may not be well-versed in the realm of "Fifty Shades" but the actress has heard of and read some parts of the book. In an interview back in 2012, Stewart even goes on to share her thoughts on the book.

"I've skimmed parts of it," said Stewart, adding, "When I read the first few pages describing her messy hair, I was like, 'This is so strange.' But it's just so raunchy! I mean, obviously, everyone knows that. But when I see people reading it on planes and stuff, I'm genuinely creeped out. Like, you're basically just reading porn right now! Get that blanket off your lap!"

Putting that thought aside, check out the slideshow and see why Stewart should be playing the role of Ana.
