It is a 1961 Twilight Zone episode about a small child with god-like powers who terrorizes a small town.
I read the original science fiction short story before I saw the Twilight Zone episode that was adapted from it. When they remade the TV Twilight Zone Series in the early 2000s, they did a sequel to the original episode 40 years later. Bill Mummy reprised his role as the "monster" with god-like powers, and Cloris Leachman reprised her role as his mother. I thought that this was a brilliant idea.
Ironically, another 20 years have passed. There is yet another new Twilight Zone series on CBS All Access. It is time for another sequel. It could set a record for having a 60-year story arc. Bill Mummy is still alive, although Cloris Leachman died in January from a combination of stroke and COVID. She played in "The Croods" animated movie that I liked and the very recently released "The Croods 2: A New Age."
