Superman Story has never stated the time when the story is set, but careful people can still guess that the story is set in 1961 through the small events in the second episode. The biggest hint is the movies and programs they watched in Mr. Incredible, such as Johnny Quest and The Outer Limits.

Although Jack-Jack Parr, the "Macey monster", is the youngest baby in the super power family, he has 17 kinds of super powers, one of which has always been to become a fireball. In the second film, Edna Mode told Mr. Incredible that Xiaojie liked Mozart very much, and in the related short film "Jack-Jack Attack" earlier in 2115, Xiaojie's nanny Kari pointed out that she would play Mozart's music while Xiaojie was sleeping, hoping to enhance his intelligence and creativity. Perhaps for this reason, when Xiaojie turned into a fireball, he often used Mozart's music as the soundtrack.

Do you remember that a bad guy emerged from the underground at the end of Superman Story? Superman Story 2 continues to have his part. Needless to say, John Ratzenberger, the voice of this underground geek, is the pig-shaped pink piggy bank "Ham" in Toy Story, and he has even voiced the characters in Disney's Bug Crisis, Monster Company, Food Story and Journey to the Dream Ring.
