I've always been a geek and slightly awkward... slightly umm... I was never the cool kid at school.
I've been quite lucky in that I've managed to tick off a few of my dream roles, really. Beyond that, you wait for the next script to come in that will have the dream role that you don't know exists yet, I suppose.
The Doctor' is the kind of character - because the guest cast is changing all the time, there are very few constants in the show, so the 'Doctor'- when you're there, you're in it a lot. You're speaking a lot.
When you're older, you want to be scared because you understand more where the boundaries between fantasy and reality are, and I suppose they are more blurred the younger you are.
I'm a good person, I hope. But I'm never as good as I want to be, never as nice as I want to be, never as generous as I want to be.
I don't think I have ever done anything for this age of children before, a pre-school audience. Generally speaking, we don't have vivid memories of that age and what influenced us, yet clearly they are hugely formative years and it's really important that we can create television of a high quality for that audience.
