Jamie Dornan said he was "really f***ing excited" when he got the news in October that he'd be taking over as Christian Grey in the movie "Fifty Shades of Grey."

The 31-year-old former "Once Upon a Time" hunk and his leading lady, Dakota Johnson, spoke to Entertainment Weekly for this week's cover story.

The man who swooped in and took over for Charlie Hunnam after the "Sons of Anarchy" star dropped out because of a busy work schedule, said he didn't mind taking on a sexy role. Dornan is married to actress Amelia Warner, and the couple are expecting their first child.

"I grew up in a very liberal place," he told EW. "I'm not shocked by the sex in the book. It's essential to tell the story. I can't believe films that don't invoke the sexual side of it. So it works for me."

The 24-year-old Johnson, set to play Anastasia Steele, is more worried about how she'll look in her birthday suit than getting extra close to the Irish actor.

"Obviously, I want to look good naked," said Johnson, the daughter of iconic actress Melanie Griffith and actor Don Johnson. "I totally understand now why people exercise, because it kind of f***ing feels awesome."

EW also reports that the release date for the movie has been moved to Valentine's Day 2015. It was originally set to hit theaters in summer 2014.

People everywhere are marking their calendars for the best date night of their lives.
