I was well aware of the fact that once you appeared in Doctor Who as something else, you were ruled out for the part of the Doctor: that was a kind of well known thing in the business.

It was lovely to do The Knock because I haven't done anything really significant since Doctor Who.

I'm perfectly proud of the work I did, looking back at it. I know I've had a bit of a revision since my 'Big Finish' stories came out.

I like challenges that test your ingenuity.

I never have reservations about doing anything as long as I'm being paid.
