In The Falling, Williams plays a student named Lydia at a girls’ school in 1969, who is the first victim of a fainting epidemic among her classmates. While Lydia is described as “intense and troubled,” she has an unlikely best friend in the more charismatic Eileen (Maxine Peake). Williams was cast in the movie less because of her acting skills, and more because of her story-telling skills, according to director Carol Morley.

“Well, Lydia’s a very complicated character,” Morley told NME. “So I wanted someone really strong who could also show a lot of vulnerability. Maisie was busy filming Game Of Thrones when we started casting, so she came in later and I got her to tell the other girls a story. I’d never seen her act, and actually I wasn’t interested in seeing her act because I wanted her to be my Lydia, not another character. But when she told the story, that was it. She was just so compelling that I knew she was right.”

Williams is best known for playing Arya Stark on HBO’s Game of Thrones, which airs Sundays at 9/8c.
