The demonstration that Mr. Rzykruski shows in class of the frog's legs twitching when given electricity is based on actual experiments in 1771 by Italian physicist Luigi Galvani, who was the first to discover that the legs of dead frogs and other dead creatures twitched and moved when sparked by electricity. This to led to the study of bio-electricity and further study of the nervous system and its functions. The study of "galvanic" effects in biology is named after Galvani, who is seen as the discoverer of bio-electricity. Several of Tim Burton's movies have played with this theme, most notably Frankenweenie and Edward Scissorhands.

While Tim Burton based the town of New Holland on a similar town in which he grew up outside Burbank, California, Disney officially chose New Holland, Pennsylvania as the town where the film takes place. After the principle of New Holland Elementary School (also the name of the school in the film) contacted Burton and the film's producers about the fictional town's similarities to New Holland, PA, Disney representatives brought movie segments and promotional materials to the school. Disney representatives also brought a parade float to New Holland's fall festival. New Holland, PA is also known for its Pennsylvania Dutch background and holds a fall festival similar to the "Dutch Day" in the film.
