- Box Office Bomb: While a confirmed or even Estimated budget has never been given, the film tanked at around 7-8 million.
- Creator Backlash:
"It was hell to make. Story was a mess. The Bagdasarians were complete assholes. They were idiots. Extremely difficult to work with. They were, for the most part reviled by the entire crew. And the process for production was insane. But some nice work did shine though."
- David Pruiksma, an animator on the film and future Disney pro, does not have good memories of working on it and refuses to rewatch it.
- Bill Plympton, who also worked on the film, but was uncredited, listed the film as one of his least favorite movies ever in his book "Independently Animated".
- Animator Bob Jaques was downright livid over being denied screen credit for his work on film. The Mighty Mouse: The New Adventures episode Mighty's Benefit Plan was made as a soapbox for Jaques to complain about the Bagdasarians' behavior.
- The Bagdasarians themselves later admitted that funding and producing the film themselves was a big mistake, citing that producers funding their own movies is the Hollywood equivalent of a lawyer representing himself.
- Cross-Dressing Voices:
- The Danza: Simon Jäger as Simon in the German dub
- Marth Debuted in "Smash Bros.": Because only the first two seasons of the 1983 show were shown in Hungary, The Chipmunk Adventure marks Miss Miller's debut in the Hungarian version.
- Talking to Himself: Alvin, Simon and Dave as well as Brittany, Jeanette, Eleanor and Theodore.
- Technology Marches On: It would have been a lot easier for Mario to be The Mole if he contacted Jamal on his own cell phone instead of Claudia's landline, which is of course what gets him caught.
- What Could Have Been:
- Production of the movie became too time consuming, and with the deadline for the completed project fast approaching, several scenes in the original script had to be re-written to make them simpler for the animators to animate (including the sacrificing scene), or cut from the script completely, thus resulting in a much shorter movie with fewer locations The Chipmunks and Chipettes actually visit.
- Early concept art also reveals that the producers originally intended to have a scene where the boys drop off a doll in a church confessional and that the sacrifice scene was originally set on top of a Mayan pyramid instead of a crocodile pit. Another sketch shows the boys in some sort of sewer or prison with two men prying open bars at an opening at the top.
