The handsome 31-year-old admitted that he and his New Worlds costar, Joe Dempsie (who also plays Gendry on Game of Thrones), got tips from Carrie, Samantha, Miranda and Charlotte by binge-watching Sex and the City prior to filming their erotic scenes.
“Joe and I watched all the Sex And The City box sets – twice. That helped,” Jamie told The Sun.
The actor and ex-Calvin Klein model added: “Obviously we were getting the work done but you’re allowed to have fun at work – I’d stop if I wasn’t having fun.”
The Northern Irish actor, who dated Keira Knightley for two years, will play Christian Grey in the highly anticipated 50 Shades film adaption, which is based on the wildly popular book series by E.L. James.
