Deliberate errors

The second season of Eighth Doctor audios featured a number of deliberate errors: The first two "mistakes" in this list were deliberate, intended to be examples of anti-time contamination. The third was also deliberate, but was explained in The Time of the Daleks. The last was not deliberate but was later retconned to be another example of anti-time contamination. Another possible example of anti-time contamination is the date. The War of the Worlds aired on 30 October 1938, yet, when he asks what day it is, the Doctor is told that it is 31 October 1938.

Later Doctor Who appearances

The episode is particularly notable in that 5 of the actors went on to star in the re-booted Doctor Who TV series from 2005, including: This does not include Paul McGann and Katy Manning who had appeared in Doctor Who prior to their appearance in this episode.
