"Well, d'you know, all I've ever revealed about what we're doing in [The Day of the Doctor
] is anything that we filmed outside. I notice people are making up stuff about who or what is or is not in that special; you're just going to have to wait till November to find out the truth.
Most of [the rumours] are quite fanciful, and some of them are entertainingly angry - people who make up their own theories about what is or is not in the special, and then make a Youtube film about how angry they are about their own theory. If you're ever bored of an evening, I recommend it as a form of self-entertainment." - Steven Moffat, TV Baftas, 2013.
Why don't we have this discussion in late November, if it's still relevant?
