The 2011 erotic novel ignited a flurry of libidos for its sado-masochistic content, but the film adaptation has been in limbo after Sons of Anarchy-star Charlie Hunnam, originally tapped to play Grey, dropped out of the project.
A number of actors were considered for the role, including Canadian actor Francois Arnaud, but Keira Knightley's former flame has reportedly won out.
The 31-year-old actor is best known in North America as The Huntsman in Once Upon A Time. He also played Count Axel Fersen in Sofia Coppola's Marie Antoinette. Jamie will star opposite Dakota Johnson, 24, who signed on in early September to play prudish coed-turned-vixen Anastasia Steele.
With Jamie reportedly as good as cast, the film is on schedule for a planned Aug. 2014 release. Can you see him as the billionaire playboy? Let us know on Facebook!
