It's official: actors Charlie Hunnam and Dakota Johnson's will be the stars of the upcoming “50 Shades of Grey” movie.

Needless to say, 33-year-old Hunnam will be playing Christian Grey. 23-year-old Dakota Johnson will be the one playing Anastasia Steel, TMZ reports.

The person to break the news was author E.L. James, who tweeted as follows:

“The gorgeous and talented Charlie Hunnam will be Christian Grey in the film adaptation of Fifty Shades of Grey.”

Furthermore, “I am delighted to let you know that the lovely Dakota Johnson has agreed to be our Anastasia in the film adaptation of Fifty Shades of Grey.”

Charlie Hunnam is best known for his role in “Sons of Anarchy.” He's got the bad boy thing going on, so I'm thinking he'll do an awesome job playing Christian Grey.

Dakota Johnson, on the other hand, has had some small roles in ”21 Jump Street,” “The Five-Year Engagement” and “Beastly.”

Something tells me the part of Anastasia Steel will be her ticket to The Land of the Utterly Famous.
