Neil Patrick Harris talks about his steamy sex scene with Rosamund Pike in Gone Girl

Los Angeles - Neil Patrick Harris was more concerned about Rosamund Pike "feeling comfortable" than people seeing his manhood when they were filming a sex scene.

The pair spent two days shooting a steamy scene for their latest movie Gone Girl, in which their characters have sex, and while the 41-year-old actor - who is married to David Burtka - insists he didn't really want anyone to look at his member, he was more worried about the blonde beauty being exposed.

Speaking in an interview with Conan O'Brien on his chat show Conan, he said: ''I was honestly more concerned about Rosamund Pike because we were having sex in the scene."

"I wanted to make sure that she in her own state of disrobedness felt comfortable and didn't feel weird, and make sure no one really, really saw my wang."

But, ultimately, the star - who plays Desi, the ex-girlfriend of Rosamund's character Amy in the film - insists actors and actresses simply have to "deal with" sex scenes as they are all part of the job.

He added: "It wasn't like we were in the musical Hair or something like that dancing around totally naked."

"There were moments where that happened and it was disarming to just, there was just, your butt is out there. There is the camera crew and that's your butt. That had to happen. You just deal with it."
