The first episode of “The Twilight Zone” was called “Where Is Everybody?” (October 2, 1959) and it followed an amnesiac man named Mike (Earl Holliman) as he wanders down a road to a small town. Although the lights are on, there are cars parked around town, and the restaurants are fully stocked, there are no people. One of the cars, in a creepy twist, features a mannequin. The solitude and his lack of memory begin to drive Mike mad. Where is everybody? Is this Hell? The episode began with the usual title sequence, wherein Rod Serling gave the following narration over Marius Constant’s famous theme music:
“There is a sixth dimension beyond that which is known to man. It is a dimension as vast as space and as timeless as infinity. It is the middle ground between light and shadow, between science and superstition, and it lies between the pit of man’s fears and the summit of his knowledge. This is the dimension of imagination. It is an area which we call the Twilight Zone.”
Incidentally, that specific recording was only used for “Where Is Everybody?” and “A Passage for Trumpet” (May 20, 1960), which aired later in the show’s first season.
