Emilia Clarke needed "vodka and some flattering lighting" to film nude scenes on 'Game of Thrones'.

She shared: "All I needed was vodka and some flattering lighting and I was ready."

The London-born actress - who had previously signed a no-nudity clause - said she found one particular nude scene to be "empowering", when her on-screen character Daenerys walked through an inferno to emerge naked.

Emilia said: "It was just a wonderful, strong moment I wanted to own, a real empowering, girl-power wow scene.

"I was so thrilled with it. It's not a sexy scene, she's not naked for no reason, it's not gratuitous. She's naked because she's just destroyed her enemies in this almighty blaze after they underestimated her.

"She played her trump card - how could I say no?"

Emilia said she has no qualms with appearing nude on screen, providing it adds to the narrative of the show or movie.

The brunette beauty told The Sun on Sunday newspaper: "If a nude scene forwards a story or is shot in a way that adds insight into characters, I'm perfectly fine with it.

"Sometimes explicit scenes are required and make sense for the characters or story, as they do in Westeros. If it's gratuitous then I will discuss with a director on how to make it more subtle."

Emilia also revealed she declined the chance to have a body double take her place in a recent nude scene, insisting she is proud of her figure.

She explained: "This is all me, all proud, all strong. That ain't no body double. I'm just feeling genuinely happy I said yes."
