Jamie Dornan has a secret weapon to help him prepare for steamy sex scenes … the box sets of Sex and the City!

That’s right, the Fifty Shades of Grey star admitted that he and his co-star, in the new miniseries New Worlds, chilled together while watching reruns of sex-filled television show and learned what characters Carrie, Miranda, Charlotte, and Samantha had to teach them.

“Joe [Dempsie] and I watched all the Sex and the City box sets,” the 31-year-old actor said. “That helped…We had a ball, it was a good fun.”

It was originally reported that Dornan was learning new moves for his role as Christian Grey, however a source confirmed that he was preparing for the romance drama that took place in England. “This was said tongue in cheek and he was referring to New Worlds, not Fifty Shades of Grey,” the source told E! News.

Dornan admits that he “had a ball” on the set of New Worlds, and was really lucky to have cast members that he could really connect and have a good time with. “We had a ball – it was a good craic,” he said. “Sometimes you don’t luck out with the cast, you end up with people who aren’t really on your wavelength and who don’t approach the game the same way but we got genuinely lucky on this,” Dornan continued. “Obviously we’re getting the work done but you’re allowed to have fun at work – I’d stop if I wasn’t allowed to have fun.”
