Johnson and Hunnam are playing the roles of Anastasia and Christian in the hit trilogy Fifty Shades.

Avid readers of E. L. James' Fifty Shades of Grey will finally have an idea on how Anastasia Steele and Christian Grey will be - or at least how they would look like on film. Like any other novel turned movie, some fans of the book are excited at how well these two will play out their roles. Others who were hoping for Ian Somerhalder, Emma Watson and Armie Hammer were not exactly as elated. There are also those who would rather not have the novel made into the movie to not ruin their already made-up ideals on how Anastasia and Christian would actually look like. Nonetheless, the movie is scheduled for release on August 2014.

Fifty Shades of Grey is an erotic romance novel published in 2011. It is the first of the Fifty Shades trilogy which also includes Fifty Shades Darker and Fifty Shades Freed. It has sold over 70 million copies worldwide and outstripped Harry Potter as the fastest selling paperback of all time.
