Bill Mumy and Cloris Leachman reprised their roles in It's Still a Good Life (2003), the only sequel in the history of The Twilight Zone (1959). Mumy's real-life daughter, Liliana Mumy, played Anthony's daughter, Audrey, who is even more powerful than he is. This episode also holds the record for the longest interval between a television episode and its sequel: 41 years, three months.
In 1974, Rod Serling finished a screenplay for a feature film version of this episode. Serling died in 1975 and the film was never produced.
Time Magazine named this the third-best episode of The Twilight Zone (1959), after Time Enough at Last (1959) and The Monsters Are Due on Maple Street (1960).
The first sentence and a half of Rod Serling's opening narration and his image with a different background inserted, is used in the Walt Disney World "Tower of Terror" attraction's pre-show video of a The Twilight Zone (1959) episode explaining the attraction. It was also used in the pre-show of the now-extinct Disneyland version of the attraction.
