* ActingForTwo: Jeremy Piven also portrays Tick Tock, [[spoiler:the real BigBad and the one who manipulated him]].
* ActorAllusion:
** Bill Paxton [[Film/{{Aliens}} gets to say "Game over!"]] in, well, ''Spy Kids 3-D: Game Over''.
** In the same film, Ricardo Montalbán as Grandpa Cortez tells people not to touch the [[https://www.youtube.com/watch?v=Vsg97bxuJnc "Corinthian leather"]] on his wheelchair.
* TheBechdelTest: The movie passes this in the first five minutes, with Carmen asking her mother for a bedtime story.
* TheCastShowoff: You thought Juni's attempt at ballet in the second film was just because RealMenWearPink? Daryl Sabara has studied ballet since he was 3.
* ChannelHop: Kind of. The first three films were released under the Creator/DimensionFilms name, but the fourth was 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.
* DisabledCharacterDisabledActor: Ricardo Montalbán was actually a wheelchair user at the stage in his life that he appeared in the Spy Kids movies. Robert Rodriguez specifically wrote the role for him.
* 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.
* FranchiseKiller: Played with. While the third film was always intended to be the last, it quickly became regarded as the weakest of the series; ultimately averted with the fourth film almost a decade later, receiving arguably even worse reviews.
* GoldenRaspberryAward: The third movie earned one for Worst Supporting Actor for Sylvester Stallone.
* 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.
* ProductPlacement: Carmen and Juni's gadgets include instant UsefulNotes/McDonalds meals.
* SequelGap: Eight years between ''Game Over'' and ''All the Time in the World''.
* WhatCouldHaveBeen:
** Angie Harmon was considered for the role of Ingrid, but her commitments on ''Series/LawAndOrder'' prevented her from participating.
** According to Robert Rodriguez, the theme park at the beginning of ''Spy Kids 2'' was originally going to be Disneyland, but Six Flags Over Texas in Arlington was used instead.
