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

Speaking in an interview with Conan O'Brien on his chat show 'Conan', which airs on truTV on Monday, 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.

"You don't mind a little, like a hint of the wang. A long, a long moment of wang, you're conscious of that. I'm fine if you see my butt and stuff like that, but you know, don't get the camera too low."

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."

UK viewers can watch Neil's interview on 'Conan' at 11pm on Monday, on truTV (freeview channel 68) - the home of larger than life characters in real situations.
