Casting buzz over the future movie adaptation of E.L. James' Fifty Shades of Grey continues to heat up the Internet at an astounding rate.

In the latest news regarding the racy flick, actress Allison Williams has now been thrust into the mix as a potential suitor to don the role of Anastasia Steele, according to International Business Times.

The 24-year-old, who plays the part of Marnie Michaels on the HBO hit TV series Girls, may just be the perfect fit for Steele with her natural beauty and seductive eyes.

The Fifty Shades of Grey premise revolves around Steele, who gets herself involved in a dominant and submissive sexual relationship with the S&M-crazed billionaire Christian Grey. Through a mutual "agreement," the two delve into the world of bondage and masochism.

Screenwriter Kelly Marcel, who is currently n the midst of penning the movie script, recently stated that it would be staying true to the book with a slew of sex and raunchiness, as the producers are shooting for an NC-17 rating, according to a write-up in Style Magazine. 

Although the Fifty Shades producers have yet to attach a director to the franchise, the film is now slated for its big screen release in the summer of 2014.

Only time will truly tell how the casting process ultimately unfolds.
