Maisie Williams, best known for her role as Arya Stark on "Game of Thrones," has revealed that portraying a schoolgirl in the new drama film "The Falling" had made her recall her own lost school days.

"The Falling," written and directed by Carol Morley, is set in 1969 and follows the story of Lydia (Williams), a neglected daughter of an agoraphobic, whose relationship with best friend Abbie (Florence Pugh) becomes strained after a puzzling case of hysteria takes place at their school.

"It was fantastic," the 17-year-old British actress said of portraying a student in an all-girls school, according to Belfast Telegraph. "On set we would speak so much about what happened to us at school, and it was so nice to do that, and go back to the years that I missed."

"Every morning coming in and saying good morning to the teacher and things like that, that was really exciting," explained the actress, who left school before receiving her General Certificate of Secondary Education to star on the hit HBO fantasy drama series. "And to be surrounded by so many girls of a similar age, chatting about the similarities and differences of being in this industry, it was lovely."

"The Falling" was screened in competition at the BFI London Film Festival at Leicester Square in London Friday, Oct. 10, The Mirror reported.

But aside from "The Falling," Williams is also busy promoting her another new movie, "Gold," in which she played a modern-day teenager - a breather from portraying Arya on George R.R. Martin's "A Song of Ice and Fire" television adaptation.

She told Irish Independent: "In a way I know what it's like to be a teenager in this world with two dads and that kind of side of it was just a lot more relatable for me and also to not have to be sort of stitched into my outfit everyday and hiding anything remotely modern and taking out earrings and things like that."

"It was nice to relax a bit more and feel comfortable and not crawling around in the mud, and no night shoots!" she added.
