The newspaper cover that rolls up the screen during the opening is an old flier advertising the appearance of "The most Revered Flagg, to elaborate on the proper devices & most godly mechanisms for the examination and discovery of wytches". Flagg is the enemy of Roland Deschain in Stephen King's 'The Dark Tower', the villain in 'The Stand', and also features in 'The Eyes of the Dragon'.
When originally broadcast, the episode's script was incorrectly credited to Ann Hamilton, when it had in fact been written by series co-creator Sam Ernst. This mistake was corrected for the DVD/Blu-ray release and an updated version of the credits now appears on iTunes.
