!!The movie:
* ActorAllusion: When Lewis asks Wilbur what his currently-absent father looks like, Wilbur lies and says "Tom Selleck." When Wilbur's father shows up at the end of the film, he looks nothing like Selleck, but he sure ''sounds'' like him... This is actually a kind of reverse ActorAllusion: the scene was written first, and gave the director the idea to offer Selleck the role.
** Played straight with international releases, where the "Tom Selleck" line is replaced by whoever's playing Cornelius (the exceptions being the Brazilian and Dutch releases).
** There's also an Author Allusion, as Goob's baseball team is the Dinos, whose mascot looks an awful lot like [[Creator/WilliamJoyce Dinosaur Bob]].
* BreakawayPopHit: ''Little Wonders'' by Rob Thomas.
* ExecutiveMeddling: [[TropesAreNotBad In a good way]]. When Disney bought Pixar and John Lasseter took charge of Walt Disney Feature Animation as well, about a third of the movie was redone to improve on the story. However, the old guard almost revolted at it and openly expressed to the press that they hoped the film would bomb.
* HeyItsThatVoice:
** Franny grows up from [[JessieFlower sounding like]] [[WesternAnimation/AvatarTheLastAirbender Toph]] to [[Creator/NicoleSullivan sounding like]] [[WesternAnimation/KimPossible Shego]].
*** Funnier thing is that they both have black hair, GreenEyes, [[DeadpanSnarker snarkiness]], they wear the color green, and are extremely [[ActionGirl good]] [[DarkActionGirl fighters]]!
** Cornelius Robinson is Tom Selleck.
*** In Japan, he's Kazuhiko Inoue, otherwise known as [[Manga/{{Naruto}} Kakashi]].
*** In {{Mexico}}, he's Jose Luis Rodriguez, AKA "El Puma".
* TheOtherDarrin: Daniel Hansen and [[Film/CharlieAndTheChocolateFactory Jordan Fry]] both voice Lewis.
* TalkingToHimself: Ethan Sandler voices no less than seven characters, mostly among the Robinson family. Director Stephen Anderson is the Bowler Hat Guy, Grandpa Bud, and Cousin Tallulah. ...yes, a female Robinson family member has a male voice for no reason!

!!The video game
* HeyItsThatVoice: Emperor Stanley is [[WesternAnimation/XiaolinShowdown Jack Spicer]] and WesternAnimation/DaveTheBarbarian.
