Fans keep shouting out their favorite stars to play the key roles of Christian Grey and Anastasia Steele in the upcoming "Fifty Shades of Grey" movie.

"Twilight" star Ashley Greene seems to be a new fan favorite to play Anastasia.

The "Fifty Shades" trilogy ("Fifty Shades of Grey," "Fifty Shades Darker," "Fifty Shades Freed"), written by bestselling author E.L. James, tells the story of 22-year-old recent college grad Anastasia Steele, who enters into a dominant/submissive sexual relationship with 27-year old sexy billionaire Christian Grey, and both explore Christian's world of BDSM while trying to understand their complicated relationship.

In a Books & Review Ana poll, Greene was in fifth place, right behind "Pretty Little Liars" star Lucy Hale. Now, Greene has surpassed Hale and is not in fourth place. "Game of Thrones" star Emilia Clarke is in third place, but Greene seems to be sneaking up and might pace Clarke, who is a huge fan favorite.

Greene recently said that she read the steamy "Fifty Shades" books.

"I feel like I kind of had to, it's now pop culture and they're making it into a film. I'm not finished with all of them, but I'm on the third book."

According to the Examiner, Greene could definitely play the part.

"Greene certainly has the beautiful, wide-eyed looks and innocent nature needed for the part," the website said.

Greene is featured as Ana on an Anastasia Steele Twitter account, @AnaRSteele."

"Recent graduate from WSU whose whole world changed when I fell into @christiantgrey's office. (Mature #50ShadesofGrey RP)," reads the description.

The 25-year-old actress plays Alice Cullen in the "Twilight" movies. Her role becomes more prominent as the "Twilight" movies progress. She plays Alice wonderfully, just like how Alice is described in Stephanie Meyer's "The Twilight Saga" novels.

One Books & Review commenter said, "Ashley Greene is definitely the on to play Anastasia...I am so surprised they have not found her yet."

Greene has some tough competition though.

"Percy Jackson & the Olympians" star Alexandra Daddario is a huge fan favorite and is current winning the Ana poll.

The 26-year-old actress was featured on Radar Online's "5 Faves for '50 Shades of Grey'" list to play Anastasia Steele. The website said, "The Percy Jackson starlet nails Ana's mix of innocence and curiosity."

Daddario is also pinned on Pinterest as a popular choice for the role. One viewer said, "Her + Matt Bomer is perfect!"

One Books & Review commenter said, "I think Alexandra Daddario is the perfect Ana. She has the long brown hair, alabaster skin, blue eyes too big for her face & pouty lips. She has an innocent beauty requiring no makeup & can be played up sexy when need be."

Another huge fan favorite is "Gilmore Girls" star Alexis Bledel. She is current in second place in the Ana poll.

The 30-year-old actress recently acknowledged her fans on Twitter who want her to play Ana.

"I see that lots of you wants me to play "Ana" in Fifty Shades of Grey. :)," Bledel wrote on her Twitter page. She won a past B&R poll, and is a big fan favorite.

Although some might say she is too old for the role, many think she is perfect.

FansShare describe Bledel with "seductive blue eyes and a stance that binds awkward charm and sex appeal."

"The way Alexis enunciates and expresses herself is also not far from the way intelligent literature graduate Anastasia carries regular conversations."
