The Fifty Shades of Grey movie has cast Dakota Johnson in the lead role of Anastasia Steele.

UPDATE: We’re all set! Actor Charlie Hunnam will play lead character Christian Grey, James announced on Twitter a hour after announcing Johnson’s role. A photo of the actor is below:

Hunnam is best known for his role in FX’s Sons of Anarchy and most recently starred in Pacific Rim. He will be in Del Toro’s Crimson Peak which is slated to begin shooting early next year.

In the book series by E.L. James, Anastasia is the leading lady who falls for Christian Grey. Now that the two leads have been cast, all eyes turn to the start of filming.

Last year, Johnson starred in the Fox comedy Ben & Kate in the titular female role, but the show was quickly canceled. She also had roles in 21 Jump Street and The Social Network, and will appear in next year’s Need for Speed.

Fifty Shades of Grey will open in theaters August 1, 2014 and will be directed by Sam Taylor-Johnson.

Reports of Johnson’s involvement with the film first surfaced two weeks ago. The same report with insider knowledge of Johnson also said that Charlie Hunman is up to be cast as Christian Grey.

James’ successful Fifty Shades trilogy went on to make the author the top earning writer of 2013.

Production on the film must move swiftly now that a lead is set. Filming is expected to begin in the next few months so that they can meet their August 1 release date.
