What you don't see backstage is what really controls the show.

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

There are generations who watch Doctor Who together.

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.

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.

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.

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