Kids should feel afraid of 'Doctor Who.' All the adults I've talked to remember fondly being afraid when they were kids. That's part of the reason they remember it and love it. And if you're afraid in a controlled way, you sort of appreciate fear in some respect.

History will only ever be partial, to a large extent history tells us what we think should be remembered and what should be forgotten, I find that really problematic.

As a kid, I knew all of the dinosaurs. It's one of those tragedies that I've forgotten what dinosaurs are cool.

As we get older - perhaps I'm just speaking for myself - we can get too cynical.

When I started Doctor Who Steven Moffat said, "That's it for the rest of your life." I'll be Doctor to a whole generation when they're 50.

When you think about it, we’re all different people all through our lives, and that’s okay, that’s good, you’ve got to keep moving so long as you remember all the people that you used to be.

We're all stories, in the end. Just make it a good one, eh?
