"Game of Thrones" Arya Stark has already revealed a more mature side in Season 5 of the HBO hit TV series. This time, Maisie Williams, who portrayed Ned Stark's youngest daughter, has moved on to a much bolder role by filming a sex scene.

Don't jump to conclusions though. Maisie Williams' intimate scenes will not be for "Game of Thrones" Season 6 but for the U.K. indie flick, "The Falling" where she portrays Lydia.

According to Australia Network, the 18-year-old celebrity disclosed in an interview with Vulture that her first sex scene was "extremely awkward."

Williams revealed, "It was extremely awkward! But [co-star] Joe [Cole] was very sensitive to the fact that I had never done a scene like this before, and it was great to work with someone who was so considerate of that."

"We went out for a couple of lunches and stuff just to get to know each other, and we had days of rehearsal where we'd get to know our characters and spend a couple of hours with each other. So I knew him quite well, and we got along quite well. It all paid off in the end."

Vulture reported that "Game of Thrones'" Maisie Williams's new hypnotic indie flick "The Falling" took place at an exclusive for girls school in the 1960s, where friendships margins on "Heavenly Creatures" — style obsession, long-hidden secrets and unresolved tensions were breaking to the surface and something seemed to contaminate a group of girls with collapsing spells. Lydia, her role, painstakingly believed that it's greater than mass hysteria and challenged school authorities, her classmates and her mother to search for the truth.

Williams shared her thoughts about her role and she said, "The reason I wanted to play Lydia in the first place was that she's such a different character than Arya. When I look at scripts, I always worry that the director isn't going to see past me playing Arya Stark or that sort of character. So I fought for this role, and Carol was really open to letting me try out."

When it came to asking for advice regarding acting, Williams was very eager to share her knowledge to her newbie co-stars but, when asked about details about "Game of Thrones," she said she would scare them about spoiling details about the succeeding episodes or season in order to keep any probing questions at bay, as per International Business Times.

"The Falling" is now available in select theaters and on VOD.
