I love playing a character that has more than 90 minutes, and that keeps going.

I think it's amazing to have one writer write every episode of a series. It's very rare, I think. You get a voice that continues.

The Victorian world is extremely dark and extremely bright.

I was lucky, I had support from Mum and Dad - they said as long as you work hard, anything is possible. I never thought past those two things - that I liked living in imaginary worlds and that it is possible to do that for a living.

The story revolved around this universal identifiable fear that we must all have, at some point, when you commit yourself to being with another person, to have and to hold until death do us part. It's a huge thing. I just felt like it was a brilliant examination of what would happen, if the person that you trusted implicitly and thought you knew every follicle and pour of, inside and out, started to not be that person anymore, inside. Physically, they're still there, but they're not there mentally.

You just want to find a story that grabs you and that you've never seen before, but somehow you can't imagine it not existing. It's like a good book. What makes a good book is hard to say. I don't know. I just look for something that grabs me. I don't have a way of looking for a project, and I don't know many people that do. It's just year to year, and what's going around and what's there.

The strength of the script, for me, was that you're really left, right till the end, to know what's happening. This seemingly perfect, happy, kooky real relationship slowly turns into something horrifying, but you get there through a filter of reality with all of it.
