For the past several months, before going to bed I have been watching my way through the DVD set, Night Gallery: The Complete Series.
https://www.amazon.com/Night-Gallery-Complete-Rod-Serling/dp/B073CY8HYG/
One of the two stories that I remember best from the series when it originally aired is “The Caterpillar.” (The other is “The Boy Who Predicted Earthquakes,” available here.)
The DVD includes several commentaries by Guillermo del Toro. It seems that I am far from the only one who remembers seeing “The Caterpillar.”
