 The actors were required to perform their movements backwards, as elements of the scene would be reversed entirely.Frank Byers, the episode's director of photography, has stated that the chief inspiration for his choice to use wide-angle lenses and soft lighting throughout the episode was the 1958 Orson Welles film "Touch of Evil".Byers also eschewed the use of additional lighting beyond that which he felt was necessary, and chose to work mainly with the natural light of the location or set in question, and to light the scene from the floor when additional light was needed.
