Trivia: Early drafts of this episode had the Carrionite invasion in 1599 (from "The Shakespeare Code") and the Dalek invasion in 1930 (from "Daleks in Manhattan"/"Evolution of the Daleks") stopped by UNIT time-travelling commandos, but this was cut for time and being unnecessary to the main plot.
Trivia: The UNIT soldier who is seen reporting that the Doctor is dead when Donna arrives at the scene the night of the Christmas Star incident is Private Harris, one of the soldiers who was mind-controlled by the Sontarans in the normal universe in "The Sontaran Stratagem"/"The Poison Sky."
