"You know, I haven’t seen the film in a very long time, but because it was another thing that my sister and I, as kids, would watch — the film Lady Jane, with Helena Bonham Carter. And Helena Bonham Carter was, I think she was like, 17. I feel funny saying that’s one of my favorite films, but it really inspired us, and we’re both actors now, and she is, to us, still amazing. When I watched it, I just remember thinking, “Oh my gosh, that’s my dream,” to play that role. I love her. Lady Jane started my love of period films and the British accent, which I’m obsessed with. I just did my first one. I did a medieval film [Ironclad] that… Do you know Jason Flemyng? He’s one of my really good friends. As soon as I heard Jason Flemyng was doing it and that it was medieval, I was like, I don’t even care what it’s about — I gotta do it just for the fun. I was the only girl on the movie. It was hilarious. And yes, I got to do my British accent."
