The decision to cast Charlie Hunnam as Christian Grey in the film adaptation of Fifty Shades of Grey has caused quite the backlash in recent days from fans of the saucy read.

Actor Charlie Hunnam continues to garner an increasing amount of attention after being cast as the S&M-crazed billionaire Christian Grey in E.L. James' film adaptation of Fifty Shades of Grey.

After landing the groundbreaking roles of Anastasia Steele and Christian Grey in the film adaptation of E.L. James' Fifty Shades of Grey, the media microscope has been increasingly zooming in on both Dakota Johnson and Charlie Hunnam's dating lives.

With the lead cast members for Fifty Shades of Grey now in place, fans are beginning to speculate just how erotic the film will get, especially the ladies, who are surely curious about how Sons of Anarchy standout Charlie Hunnam will clean up in order to get down and dirty in the Red Room of Pain as Christian Grey.
