The Adventures of Jimmy Neutron: Boy Genius

It was originally supposed to air as a short on KaBlam!, but the show got canceled before the episode aired.

The pilot had a few differences from the main series.

The show began with Jed Spingarn as story editor and Steven Banks as head writer, though the series featured a variety of freelance writers as well.

Davis created Jimmy (then named Johnny Quasar) sometime during the 1980s and wrote a script titled Runaway Rocketboy (later the name of the pilot), which was abandoned.

The pilot involves Jimmy Neutron testing a rocket ship that he has invented, and later uses it when he inadvertently stumbles upon a Yolkian plot to conquer Earth.

The pilot was aired in short mini-episodes on Nickelodeon before the film's release, and its plot was used for the film.
