Jimmy was still called Johnny Quasar before it was decided to name him Jimmy Neutron because the name sounded eerily similar to Jonny Quest. 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. It was later included as an extra on the "Confusion Fusion" and "The Complete Series" DVDs. 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. In it, Jimmy did not wear his signature red atom shirt, Judy's hair was darker, the Yolkians all wore grey suits and King Goobot's crown was a different color, the theme song was longer with a few lines that were cut later, Goddard was voiced by Kim Saxon, instead of Frank Welker, Carl Wheezer resembled his father, Sheen Estevez was absent and the title card had a picture in the scene. Writing The main writers when the show was greenlit were Steven Banks and Jed Spingarn. Animation DNA Productions retooled their pipeline when moving from the film to the TV series, to reuse assets for the episodes. Some of the programming team at the studio programmed a special code that allowed the animators to animate scenes in Maya, which can then be rendered in Lightwave. This helped the team keep up with the deadline and avoid going over budget. Possible reboot/revival plans In 2016, director John A. Davis has stated that he has a story for a Jimmy Neutron reboot feature that he would like to make, but he is waiting for the "right situation" to make it. When asked about a reboot in 2020, Rob Paulsen stated "Well, I've got to tell you, man. I go all over the world when we don't have the coronavirus, and people love Carl. They love Carl. I don't think it would be a bad thing at all to reboot Jimmy Neutron. I think that's one of those shows that a lot of people would love to see again. It was very good. Really smart. That wouldn't surprise me." Theme song The theme song was originally written by Brian Causey for the pilot episode.
