Trivia / The Adventures of Jimmy Neutron: Boy Genius
Accidentally Correct Writing: Despite coasting along on Rule of Cool, the show sometimes got something right even when the writers obviously weren't even aiming for accuracy. One such highlight occured in Sorry, Wrong Era when Jimmy shattered the big diamond in an attempt to break off a chunk small enough for his jury-rigged Bamboo Technology time-warping device. Diamond, while certainly the hardest natural substance on earth, is also brittle enough to shatter using little more than a hammer, chisel, and a little bit of precision.
Sam's Verbal Tic ("Yeah!") is a reference to The Weird Al Show, where in the first Adventures of Fatman segment, Billy West played Al's Evil Uncle Frank, who plotted to flood the city and loot it using melted ice cream; the voice and tic was carried over from Frank. DNA Productions, before getting into 3D animation, animated the Fatman segments.
In "Win Lose or Kaboom", Hugh manages to win the game show with a single question, including a car. His voice actor, Mark DeCarlo, won a car (along with a boatload of other prizes and cash) on Sale of the Century in 1985; he managed it by tying with his opponent in the Speed Round and the opponent answered the tiebreaker incorrectly, sealing his win.
Early Draft Tie-In: The game for Attack Of The Twonkies uses Cindy's design from the movie instead of her older looking, pigtail-less design from the actual series.
He Also Did: Mark DeCarlo, voice of Hugh Neutron, was a lot winner on the 1980s NBC run of Sale of the Century, hosted the relationship game show Studs in the early 90s, and currently appears on ABC's The Chew.
King Goobot and Ooblar were voiced by S. Scott Bullock and Paul Greenberg in the original pilot. Patrick Stewart and Martin Short replaced them for the movie, but Bullock and Greenberg reprised their roles for the series.
The mayor of Retroville was voiced by Mark DeCarlo in the episode "Normal Boy" and by Jim Cummings in all subsequent appearances.
Sheen's dad went from being voiced by Carlos Alazraqui in the movie to being voiced by Joe Lala in the series.
Recursive Adaptation: Attack of the Twonkies- originally a spinoff game- got its own special that majorly diluted the game's plot. The twonkies became a Canon Immigrant after this, appearing every now and then as an Easter Egg.
Saved from Development Hell: The original storyboard was created in the 1980s. It was later revived as a 40-second test animation called Johnny Quasar in 1995, and later again as a short called Runaway Rocketboy in 1998. The 1998 incarnation was picked up by Nick a few years later and thus the film was made.
Troubled Production: One animator who worked on the show summed up working on it by saying "We just didn't have the time or money to care." The show was very low budget and had insane deadlines (they only had three weeks to slam together each episode), they didnt even have an art department, nobody had any idea what was going on during production, and the power would go out at the studio at least once a week.
Originally, the show was going to be called Johnny Quasar. A video intro was found of this early form, but not much else came from it. Early designs were very different from the final draft such as Jimmy's parents◊ and friends◊, but not Goddard,much◊. In the short, the neutron logo was a "Q" instead of an atom.
Libby was a last minute inclusion but she looked vary different at one point.
The main theme was slightly longer with a couple more lyrics.
According to the show's page on The Other Wiki, there was going to be a fourth season, which would've been Darker and Edgier. First, the season premiere episode "Deep Impacts" would've shown Jimmy's Final Battle with Evil Jimmy. Another episode would feature Cindy and Betty interacting with each other, Cindy and Jimmy would've finally become a couple, and Nick, who was basically Demoted to Extra in the show, would've gotten a larger role. Finally, there were going to be more appearances from the League Of Villains.
