Answering incredibly nerdy questions that never really needed to be answered is pretty much Steven Moffat's Whovian raison d'être. But with the writer now having left the show, he isn't going to get the option to do that in an official capacity for a while... that is, outside of a new Doctor Who novelisation.

Steven Moffat has made it clear that the version of "The Day of the Doctor" that made it onto screens for Doctor Who's 50th anniversary celebration was far from the first iteration. An early draft, which reunited the Tenth and Eleventh Doctors with the Ninth incarnation, was scrapped when Christopher Eccleston declined a return - and now samples of that script are being released for the first time.
Steven Moffat has long made it known what an insanely stressful time the creation of Doctor Who's 50th anniversary special was - an event almost so disastrous it nearly didn't have the Doctor in it at all. But at long last, Moffat has revealed what story he would have had to use for the potential reality of "The Day of the Doctor" with no Doctor.
