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

I'm a terrible person for carrying things around. I carry everything around with me, it's like my home.

In the studio, if they need to come down to the floor, things are a bit pushy, although it is easier for them to say things directly rather than through about five people.

I'm not really a science-fiction fan, I quite like the idea of getting away from the science-fiction side of it, for two episodes. It was lovely, it was a super story and great fun.

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.
