Anna Maxwell Martin

I was always a show girl. My parents were wonderful. There wasn't a lot going on where we lived, but they ferried me to classes and competitions all over the place. When I was 12, I came to London as a finalist in a singing competition and I was completely wide-eyed.

At one point, my house was a school for autistic children. I opened up my doors to about 30 kids and their families at the time. I was turning into Mary Poppins because I had to do something for these kids who have nowhere to go. So my house was the school for two years.

When I have a creative insight, there is a high. I think back in the day, I made music as much as I did because it made me feel so good. I think you could argue that there is a creative addiction - but, you know, the healthy kind.
