Game of Thrones” isn’t shy about showing off its lurid side, whether it be grisly violence, or on-screen nudity.

“It’s only right, if you’re going to make a show where nudity and sex is a large part of it, that you be a part of that,” Kit Harington, who plays Jon Snow on the HBO series, says in the April issue of GQ.

But when asked if  he’d be comfortable in the nude on-screen, the 27-year-old, who recently starred in “Pompeii”, hesitated.

“I’m not saying. Because I don’t know. It would have to be f–king well deserved,” he countered.

While Harington’s rear end made an appearance in season 3, the actor who’d just broken his ankle, wasn’t forced to disrobe — instead a crew member acted as his butt double.

“When it came down to it I had a broken ankle,” he says, “so the only time you saw my ass, it wasn’t my ass.”

Game of Thrones” returns to HBO on April 6.
