Speaking at the Doctor Who 50th Celebration at London's ExCel, Moffat said: "He has no more ever called himself the 11th Doctor than he would call himself Matt Smith. The Doctor doesn't know off the top of his head [what number he is].
"If you worry about such things, and I do, then I specifically said John Hurt's Doctor doesn't use the title. [Matt Smith's Doctor] is in his 12th body but he's the 11th Doctor, however there is no such character as the 11th Doctor - he's just The Doctor, that's what he calls himself.
"The numbering doesn't matter, except for those lists that you and I have been making for many years. So I've given you the option of not counting John Hurt numerically - he's the War Doctor."
