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.

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.

Doctor Who is like any long-running series in that the cast tend to look to the star to set the general tone. Rehearsals and filming could be a lot of fun.

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.

I'd like to do some more classical work if I do some more theatre.

When we went to Belfast we saw some beautiful countryside and coastlines.
