Question: Who played the War Doctor?

Answer: John Hurt

Question: In what episode does the "Fall of the Eleventh" happen?

Answer: The Time of the Doctor

Throughout the programme's long history, there have been revelations about the Doctor that have raised additional questions. In The Brain of Morbius (1976), it was hinted that the First Doctor may not have been the first incarnation (although the other faces depicted may have been incarnations of the Time Lord Morbius). In subsequent stories the First Doctor was depicted as the earliest incarnation of the Doctor. In Mawdryn Undead (1983), the Fifth Doctor explicitly confirmed that he was then currently in his fifth incarnation. Later that same year, during 1983's 20th Anniversary special The Five Doctors, the First Doctor enquires as to the Fifth Doctor's regeneration; when the Fifth Doctor confirms "Fourth", the First Doctor excitedly replies "Goodness me. So there are five of me now." In 2010, the Eleventh Doctor similarly calls himself "the Eleventh" in "The Lodger". <hl> In the 2013 episode " The Time of the Doctor ," the Eleventh Doctor clarified he was the product of the twelfth regeneration, due to a previous incarnation which he chose not to count and one other aborted regeneration. <hl> The name Eleventh is still used for this incarnation; the same episode depicts the prophesied "Fall of the Eleventh" which had been trailed throughout the series.
