- Adaptation Displacement: Many people may not know about the original booknote by artist Stewart Moskowitz which was first published three years earlier. On the other hand, other than allowing the use of his characters, he wasn't directly involved in the making of the movie.
- Anvilicious: About everything from honesty to sportsmanship to proper piano technique.
- Anti-Climax Boss: The final duel between Rob and the main villain is ridiculous and uninteresting. It starts with him kidnapping the moose child at the dam and leaving him on a rock in the middle of ankle-deep water close to the heroes and ends with Vultor losing control of his flight in a snowstorm.
- Ass Pull: Everywhere. From the Legacy to the lightning powers to the world domination scheme involving chocolate. It's all there.
- Awesome Music: The music for this was done by Howard Kaylan and Mark Volman, AKA Flo (Volman) and Eddie (Kaylan), of The Turtles, The Mothers Of Invention and Down and Dirty Duck fame.
- Designated Hero: Rob constantly misses opportunities to stop the Jackals throughout the movie, and only directly stops about two of them by the time the movie's over.
- Ensemble Dark Horse: Ping, the Garfield-voiced gorilla. Supposedly, besides attempting to make money to rebuild a bar, the characters traveling with Rob believe that they have a "duty to fight against evil," but out of all of them, Ping is the only one who actually does anything against the Jackal antagonists. In fact, he's probably more effective than Rob is, American Rabbit or not.
- Ham and Cheese: Kenneth Mars deserves credit for taking this route as the Big Bad Walt; his performance is the only thing everyone remotely enjoys about this movie.
- Hilarious in Hindsight: The penguins in New York City bear a surprising resemblance to those of Club Penguin.
- Suspiciously Similar Song: The main theme to the movie is this to John Williams's Superman theme.
- The Jackals' theme sounds very similar to Foghat's "Slow Ride".
- They Wasted a Perfectly Good Plot: In the movie, it is mentioned that not all jackals are bad. However, every jackal seen in the movie is a villain. They could have had Vultor decide that the jackals were no longer useful to him and leaving them to die on the burning boat in New Orleans. Robert could have saved them, leading to a HeelFace Turn.
- The movie could be seen as They Condensed a Perfectly Good Plot. If this were a 65-Episode Cartoon or similar series, there would be more than enough time for proper World Building and Character Development, and for each major setpiece to warrant a full episode, among other things. As it is, it plays more as a Random Events Plot where things just happen in quick succession.
- What Do You Mean, It's for Kids?: The film tends to zigzag this with its violence, but the surprising amount of talk about morals and taking political action (such as nonviolent protest) would probably bore and/or confuse kids.
