Charlie Hunnam is out, and sources are now pointing to Jamie Dornan as the new Christian Grey. But who exactly is Jamie Dornan?

The newest addition to the Christian Grey rumor mill may not be as well known as Hunnam, who allegedly dropped out due to scheduling conflictions caused by "Sons of Anarchy," but the Irish model certainly has right body to portray the hyper sexual businessman who dominates Anastasia Steele (Dakota Johnson, 21 Jump Street).

Dornan first gained fame as an underwear model for Calvin Klein. His modeling career took off with spreads for Armani, Christian Dior and Aquacutum. He has even modeled with legend Kate Moss.

The model then made the switch to acting with a small role alongside Kirsten Dunst in Sofia Coppola's Marie Antoinette. From 2011 until 2013, Dorman played Sheriff Graham/The Hunstman in "Once Upon a Time." The model-turned-actor then confirmed his acting legitimacy by playing a serial killer in "The Fall," a BBC drama.  

"The Fall" has helped Dornan practice getting kinky in front of a camera, a useful experience for a possible Christian Grey.

"I spent a day strangling myself on the back of a door while I masturbated to a driving license of one of my victims...that's not an easy day at the office, and they cut it out," Dornan told Digital Spy.  "I couldn't believe it-they didn't even tell me. When I first watched the series, it just wasn't there!

You may also recognize Dornan from his relationship with Keira Knightley. The pair met on the set of an Asprey photo shoot and dated from 2003 until 2005, Telegraph reports.

Dornan will have to out-Grey a slew of actors rumored to be under consideration for the Fifty Shades of Grey lead role including Christian Cooke, Theo James, Cillian Murphy, Alex Pettyfer, Ian Somerhalder, Alexander Skarsgard and fan favorite, Matt Bomer.
