The "melting paintings" effect at the end of the episode was done by painting the pictures in wax on a hotplate and then turning the hot plate on and tilting it. (edit) Included on volume 15 of Image-Entertainment's DVD collection. (edit)

Closing Narration
Narrator: "The poles of fear, the extremes of how the Earth might conceivably be doomed. Minor exercise in the care and feeding of a nightmare, respectfully submitted by all the thermometer-watchers in the Twilight Zone." (edit) Opening Narration
Narrator: "The word that Mrs. Bronson is unable to put into the hot, still, sodden air is 'doomed,' because the people you've just seen have been handed a death sentence. One month ago, the Earth suddenly changed its elliptical orbit and in doing so began to follow a path which gradually, moment by moment, day by day, took it closer to the sun. And all of man's little devices to stir up the air are now no longer luxuries - they happen to be pitiful and panicky keys to survival. The time is five minutes to twelve, midnight. There is no more darkness. The place is New York City and this is the eve of the end, because even at midnight it's high noon, the hottest day in history, and you're about to spend it in the Twilight Zone." (edit)

This episode does not have any trivia. Add some now!

Just before she collapses, Mrs. Bronson looks at the painting of the waterfall and says it reminds her of the tallest waterfall in Ithaca, New York. The reference is possibly to Taughannock Falls in Taughannock State Park, 11 miles north of Ithaca. Rod Serling taught at Ithaca College and lived in the Ithaca area for several years. (edit)
