I swing between procrastination and being really thorough so either way things aren't getting done quickly.

I appreciate individualism.

I know it's really square but I'm one of those people who piles on the factor 50 as soon as I'm outside.

David Tennant is a massive fan, and grew up dreaming he would be the Doctor Who one day. So I did feel, when I first got the job, "Right, now I've got to do loads of research into absolutely everything Doctor Who." But that's not possible to do in a short space of time. So my knowledge has been growing and developing as I've been doing it, and that's been fine. That's been appreciated by the fans, and the executives never expect me to be brushed up on absolutely everything.

I always have to have breakfast before I leave the house, even if it's 4 A.M. and I'm not hungry.

I'm one of these people that if I have a nice holiday - like I have had in Turkey repeatedly - I go back a lot.

I don't have an iPod! It's never appealed to me, really.
