It sounds so negative of me to say, but I don't feel like there were many coming-of-age films when I was growing up. I think that when I was a teenager, I felt really misrepresented in the teenage roles that I was watching onscreen. Especially in women.

Diary of a Teenage Girl' was my first American movie. It was my first movie in an American accent. It's based on a graphic novel, which was written in 2002 by someone called Phoebe Gloeckner. It was turned into a play by Marielle Heller, who then wrote it as a screenplay for Sundance Labs.

When I was young, there weren't any teenage girls I could relate to in film. They were all put in boxes: the virginal good girl, the really sarcastic asexual one. I wanted to do something that represented how I felt then.

I think that Hollywood misconstrues actresses saying, 'Oh I wanna play a strong female character,' like we all want to play, like, superheroes or something.
