Maisie Williams of Game of Thrones fame says filming her first-ever sex scene for the film, The Falling, was a little bit “awkward.”

“It was extremely awkward!” Williams, 18, told Vulture magazine.

OK, it was more than awkward.

Maisie Williams plays Lydia in the indie film about students who attend an English all-girls school in the 1960s. Her sex scene was with costar Joe Cole who Maisie said “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.”

To prepare for the scene, Williams said she and Cole just hung out together on and off the set.

“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,” said Maisie.

While Maisie Williams was able to hang out with Cole, she was told to keep her distance from Maxine Peake, who plays her estranged mother in the film.

“Carol [Morley], our director, told Maxine not to communicate with me and to keep her distance, so she wouldn’t create a relationship with me — because within the story, our characters don’t have a relationship. But Carol hadn’t told me she was going to do this! So here I am, trying to make contact with Maxine every single day, trying to make it work, and her never giving anything back,” said Williams. “Throughout the shoot I was so miserable because I thought she hated me. I thought all the adults hated me, and I had no idea why. I was just trying to prove myself and be a good actress.”
