I loved playing [the Doctor], and taking part in the basic essence and message of the series which is, it's a short life, seize it, and live it as fully as you can. Care for others. Be respectful of all other life forms, regardless of colour or creed. To be part of that was fantastic.

I had to help to coax the performances and I really enjoyed that extra responsibility.

I think the themes of belonging and parentage and love are obviously universal.

When you seek revenge, be sure to dig two graves.

The person who gives you your first job is so important in any industry.

I don't like to watch playback. But being on the set, watching the way the camera is being moved and the way the light is being used, you do get an idea of it.

I had bags of energy as a kid.
