The park in the episode is said to be inspired by Recreation Park in Rod Serling's hometown of Binghamton, New York. Like the park in "Walking Distance", Recreation Park has a carousel and a bandstand. There is a plaque in the Recreation Park bandstand commemorating the episode.
A sign at the gas station reads, "Service station, Ralph N. Nelson, Prop." Ralph W. Nelson was the production manager for most Twilight Zone episodes including this one.
This is the first of only four episodes of The Twilight Zone (1959) in which Rod Serling uses a mid-episode narration. The other three are Time Enough at Last (1959), I Shot an Arrow into the Air (1960) and I Sing the Body Electric (1962).
The episode was filmed predominantly at sets built for Meet Me in St. Louis (1959). The carousel used in the episode was a rental.
One of the names that Martin Sloane mentions when he first walks through Homewood, reminiscing about people he knew there as a child, is "Dr. Bradbury." This was an acknowledgment by Rod Serling., the screenwriter of this episode, of the debt he felt toward author Ray Bradbury, who was one of the science fiction writers who inspired Serling.
