With being a mother, I feel like you choose how you spend your time so much more carefully - which is a good thing.

I feel like I've always had two selves - the part of me that makes films and the part of me that's political, and they haven't really connected that much. Alias Grace talks about things like class and immigration and women's rights, which felt really good. But especially now, there are pressing things to be said. It's a really scary time in the world. It's a very scary thing to have an American president who openly brags about assaulting women and is openly racist. This isn't a moment to be speaking in metaphors.

It's hard to give up that amount of control. It's scary to make yourself that vulnerable. Because you might do all kinds of things that are unplanned or are unexpected that maybe don't work, and you have to trust the director to see that and work around those things. I find it really scary.

I've always been such a fan of short films - in fact, I never considered that I would actually make a feature. I just thought I wanted to make shorts for the rest of my life. They are a lot harder to have shown and a lot harder to find and see as an audience, but I don't know. It's just a form that I really love. I was just making them for the process, but ultimately, I did get them into festivals, and they did end up on television, and they had as much of a life as short films can.

I am aware that I've generally been more attracted to introspective roles, but it's sort of bizarre, because it's the opposite of who I am in many ways. I think I'm quite an extroverted, loud person. So it interests me that that's sort of the place that I go all quiet, is when I'm onscreen. It's a bit strange.

Plus, doing a zombie movie is quite liberating. It's fun not to take myself seriously all the time.

I think it's a universal thing in every family, that people have their own specific versions of pivotal events or even small memories.
