Universal Pictures and Focus Features formally announced the news on Monday, shortly before confirming Charlie Hunnam will play the male lead, Christian Grey.
The highly-anticipated film will be based on E L James’ best-selling erotic novel.
“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,” the author tweeted.
Johnson, who previously starred in The Social Network and on the FOX series “Ben and Kate,” is the daughter of Melanie Griffith and Don Johnson.
The casting follows months of wrong rumors and speculation about who would land the coveted role.
The movie, to be directed by Sam Taylor-Johnson, is set to be released on August 1, 2014.Follow @Infocelebrity on Twitter!
