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 haven't been approached to do a 'Doctor Who' movie. I think they would be scraping the bottom of the barrel if they asked me to do it.

One of my grandfathers, actually, having gone out there as a minister, decided he would better serve the people as a doctor. So at a very late age - at the age of 38 in fact - he changed course and decided to become a doctor.

Don't let adverse facts stand in the way of a good decision.

We are pleased that the Supreme Court ruled in our favor. The fact that the court was unanimous confirms what we said from the start: this case had no merit.
