I thought The Visitation was good fun. We did some of that filming at Ealing on the big set.

The cybermen are good monsters, I think. My earliest memories are of the cybermen from when I used to watch when I was younger. It's nice to have them back.

I went to ballet school for nine years, and there was an agent for the whole school who happened to be there visiting one of the performances. She suggested an audition.

I don't know if you've ever tried writing a Doctor Who story, but it's a lot more difficult than it initially appears, especially if you've got more than one assistant.

After two years of doing one show, you do get attached to everyone.

Before I got Doctor Who, I went to the Guildhall School of Music and Drama. I went back to take the final grade exam, which is the grade you have to take before you can take the teachers diploma.

I often look at a lot of Doctor Who stuff that's about now, which no one has approached me about.
