Northern Irish star Jamie ,32, has revealed contracts were signed ahead of filming to ensure his private parts stayed, well, private.
Chatting to The Guardian, the dad-of-one said: "There were contracts in place that said that viewers wouldn't be seeing my, um… todger."
"You want to appeal to as wide an audience as possible without grossing them out. You don't want to make something gratuitous, and ugly, and graphic," he added.
Jamie stars as mysterious billionaire Christian Grey in the upcoming movie, based on the erotic novel of the same name by E.L. James.
As you'd expect in a erotic fiction, there are sex scenes aplenty.
But Jamie says they were definitely NOT sexy to film alongside co-star Dakota Johnson, who plays naïve publishing graduate Ana Steele.
"Anyone who thinks actors get turned on doing sex scenes in films is mistaken. There are dozens of hairy men standing around, moving cables and lighting equipment. That's not sexy unless you're into being watched, which I'm not."
Jamie also admitted that he knows not everyone who loved the book series will appreciate the movie.
"I am never going to please all 100 million people who read the book," he says. "I'll be lucky if half that number are happy with me playing Christian Grey. I know there are campaigns of hate against me already."
Not from Reveal, we can assure you!
