It has been a wild two weeks for all those involved with the 'Fifty Shades of Grey" movie adaptation, but the film has reportedly found its leading man.

Jamie Dornan, 31, will step in as the coveted role of bondage businessman Christian Grey after Charlie Hunnam dropped out earlier in the month because of a hefty workload that prevented him from adequately preparing for the movie, according to Entertainment Weekly and Variety.

So, who is Jamie Dornan?

"Once Upon a Time" fans know exactly who this former Calvin Klein model is because he played the sexy sheriff of Storybrooke, before breaking hearts everywhere when he was killed off by the evil queen.

The studios have declined to confirm the news, but Entertainment Weekly and Variety have reported the casting of the Irish actor, saying that negotiations are in the final stages. Reps for the actor have not responded to ABC News' request for comment.
