Behind the scenes

 * In an early draft of The End of Time, Russell T Davies had the Tenth Doctor address the "half-human" statement the Eighth Doctor made in the 1996 TV movie, dismissing it as "a forty-eight-hour bug". The line was cut by Davies for several stated reasons, including the fact it would have confused viewers who were only familiar with the events of the episode Human Nature.
