Matt (on being cast as the Eleventh Doctor): I'm flabbergasted. I haven't slept really to be honest. Truthfully, I haven't. I probably look a bit 'bags under the eyes' now because it's sort of an iconic part of our culture. My granddad knows about it, my Dad knows about it, it's been around since 1963 and I think it has the iconic kind of status that Robin Hood or Sherlock Holmes have and I'm sort of taking that on.
