THE THREE DOCTORS

Here is a unauthorized photo which clearly was taken under rushed conditions and not very clear looking.  This is from the upcoming 50th Anniversary Special in which Matt Smith as Doctor Who #11, David Tennant as Doctor Who #10 has a conversation with actor John Hurt (Who is also an official edition of Doctor Who, but not the twefth edition because that's played by Peter Capaldi.  I'm honestly not sure where Producer Steve Moffat is going with this one.  Anyway, in this photo, Matt Smith as Doctor Who #11, David Tennant as Doctor Who #10 and John Hurt (Children of a Lesser GOD) as Doctor Who #Unknown Number hangs out in the control room of Doctor Who's time travel spaceship the Tardis (Which looks like a telephone booth painted blue).

 John Hurt as Doctor Who #Unknown Number in his official colorful action costume super-suit uniform attire.  What John Hurt as Doctor Who #Unknown Number did he was compelled to do.  Not just for sanity, but also for peace.  But what he did, he didn't do it as the Doctor.  Because he was the only incarnation of Doctor Who who broke the promise (Whatever that means).
