* ActorAllusion: Bill Paxton [[Film/{{Aliens}} gets to say "Game over!"]] in, well, ''Spy Kids 3-D: Game Over''.
* ChannelHop: Kind of. The first three films were released under the Creator/DimensionFilms name, but the fourth will be released under the Creator/{{Disney}} name. However, Dimension Films was (at the time) distantly owned by Disney, so technically they were always Disney films even if they didn't have the Disney logo at the beginning.
* DyeingForYourArt: Courtney Jines for the third movie
* ExecutiveMeddling: The fourth film. Rodriguez didn't want to make another one and was in no hurry to make another film for producer Harvey Weinstein after he was single-handedly blamed for the failure of ''Film/{{Grindhouse}}''. However, he owed Weinstein one more movie in a contract signed before that movie was released and Weinstein wanted a sequel. ''All The Time in the World'' was the result.
* FakeMixedRace: Juni certainly doesn't look like he could be Antonio Banderas' son.
** And let's not forget that Juni's mother is mixed-race herself. After all, ''her'' father is Ricardo Montalbán.
* HeyItsThatGuy: Look out for Emily Osment before ''Series/HannahMontana'', Taylor Momsen before ''GossipGirl'' and Selena Gomez before ''Series/WizardsOfWaverlyPlace''.
** [[Film/MenInBlack Jeebs]] plays Alexander Minion.
*** [[HilariousInHindsight Holy crap, did anyone else just realize that Tony Shaloub would go on to play another character with the initials]] [[{{Monk}} "A.M."]]?
** Karen Sisco.
** [[Film/TheLordOfTheRings Frodo]] is the '''REAL''' guy in the third movie. Gets approx. 1 minute of screen time.
*** This may be a cross between a TakeThat and ActorAllusion.
*** This is why you don't simply walk into Mordor.
** Oh hey, [[TheBigLebowski Donny]] is the bad guy in the second movie.
*** The bad guy? I don't think so. Mad scientist, maybe, but he DOES help the main characters at the very end.
** And Rocky is the bad guy of the third.
** [[RetroactiveRecognition In a reverse sense,]] viewers of RepoTheGeneticOpera will recognize a very young Shilo.
** The first movie had [[Film/{{X-Men}} Nightcrawler]], [[LoisAndClark Lois Lane]], and [[TheMaskOfZorro Zorro]]!
** Donnagan Giggles is played by [[Creator/MikeJudge that one dude]] who [[KingOfTheHill has done]] [[BeavisAndButthead a few animated]] [[TheGoodeFamily tv shows]] and [[OfficeSpace directed]] [[Film/{{Idiocracy}} a few]] [[{{Extract}} movies.]]
** Mr. Lisp is [[WesternAnimation/AvatarTheLastAirbender Piandao]], [[{{Terminator}} T-1000]], and one of the mooks in Film/DieHard2.
** Uncle Felix is Cheech. Yes, ''that'' Creator/{{Cheech|AndChong}}.
** [[Film/StarTrekIITheWrathOfKhan Khan]] appeared in the second and third movies as Juni and Carmen's grandfather.
** Francis is [[VideoGame/FinalFantasyXII Vaan!]]
** In France, Ms. Gradenko is [[Disney/TheLittleMermaid Ariel]].
* KeepCirculatingTheTapes: The 3D version of ''Spy Kids 3D'' on DVD went out of print after Lionsgate purchased most of the Miramax library and wasn't released on Blu-ray until 2012, over a year after the film's initial Blu-ray release.
* PlayingAgainstType: Danny Trejo as a good guy in a kids' movie, Creator/MikeJudge of all people as the BigBad in ''Spy Kids 2'' and, of course, Robert Rodriguez was ''[[SoMyKidsCanWatch directing]]'' against type.
