"The Incredible World of Horace Ford" is an episode of the The Twilight Zone.
"Mr. Horace Ford, who has a preoccupation with another time, a time of childhood, a time of growing up, a time of street games, stickball and hide-'n-go-seek. He has a reluctance to go check out a mirror and see the nature of his image: proof positive that the time he dwells in has already passed him by. But in a moment or two, he'll discover that mechanical toys and memories and daydreaming and wishful thinking and all manner of odd and special events can lead into a special province, uncharted and unmapped, a country of both shadow and substance known as... the Twilight Zone."
Horace Ford is a 38-year-old toy designer whose life is dominated by blissfully happy memories of his childhood. His colleagues, wife, and mother have all become increasingly frustrated with his obsession.
One day, he decides to revisit his childhood neighborhood. Ford discovers, to his amazement, that it has not changed. He recognizes the boys he played with in his childhood—who have not aged. Frightened, he returns to his apartment, but he visits his old neighborhood again on each of the next several nights. Each night the same scene plays out and he stays slightly longer, before returning to his apartment.
On his last visit, he stays much longer than before, and hears his old friends complaining about him. He tries to talk to them, and suddenly turns into a boy again. His friends bully and assault him, as Horace realizes that his childhood was not as pleasant as he would nostalgically recall. After his wife finds him, he "grows up"—returning to his own time period and age group with a new-found appreciation for life as an adult.
"Exit Mr. and Mrs. Horace Ford, who have lived through a bizarre moment not to be calibrated on normal clocks or watches. Time has passed, to be sure, but it's the special time in the special place known as - the Twilight Zone."
