The film's premise has Retroville being enslaved by a race called the Coractians and Jimmy and company must save their hometown.

A sequel for Jimmy Neutron: Boy Genius was in development under the title Jimmy Neutron 2: The Search for Carl, but never materialized and was cancelled over agreements on a story and the existence of the subsequent TV series The Adventures of Jimmy Neutron, Boy Genius.

Development
A sequel for Jimmy Neutron: Boy Genius was in development for a summer 2004 release back in February 2002. Former producer, Albie Hecht, reported to The Los Angeles Times that it "would be made on the same budget as the first, but with a new batch of inventions and adventures in Jimmy's town of Retroville." In June 2002, Kate Boutilier had signed on to write the sequel under the title Jimmy Neutron 2: The Search for Carl, but the sequel was never materialized; its plot was instead used for the Game Boy Advance version of the video game Jimmy Neutron vs. Jimmy Negatron. Also furthering its cancellation was that the writers could not agree on a story and Keith Alcorn later stating in an interview that "once [The Adventures of Jimmy Neutron: Boy Genius] came out, there wasn't a lot of incentive to make a movie when fans could simply watch Jimmy Neutron for free at home."

Following the announcement of the Nicktoons Cinematic Series, production on the sequel was rekindled with John A. Davis returning as director and writer. During writing on the sequel, it would serve as a continuation to the series. The premise itself was originally to focus on Jimmy setting out to save his friends when they get abducted, but was reworked to distance itself from similarity towards its predecessor and the subsequent entry Teenage Robot Beyond Tremorton; the sequel was set in Retroville with an alien race overtaking the town. Following Davis' production company DNA Productions having closed down in 2006, animation on the sequel was provided by Bardel Entertainment.

Casting
The original cast of the franchise signed on to reprise their roles, including Debi Derryberry and Crystal Scales. Kelsey Grammer was cast as Vaz, a tyrannical ruler of the planet Coractia; Grammer had previous voiced antagonistic characters such as Sideshow Bob from The Simpsons and Stinky Pete from Toy Story 2. Brie Larson was cast as Coractian worrier Vex. Idris Elba and Bill Hader were cast as Coractian head guards Kan and Yaw, whose interactions are reminiscent to comedy duos Laurel and Hardy and Abbott and Costello with Hader's character as the straight man opposite Elba's. Eugene Levy as Vex's father Viz, making this his third animated role as a father after Over the Hedge and Finding Dory. Additionally, Ty Burrell was cast as Vaz's general Og.
