Individual films
- Spy Kids
- Spy Kids 2: Island of Lost Dreams
- Spy Kids 3-D: Game Over
- Spy Kids: All the Time in the World
The series as a whole
- All-Star Cast: Let's see... Antonio Banderas, Danny Trejo, Alan Cumming, Tony Shalhoub, Salma Hayek, Mike Judge, Elijah Wood, Robert Patrick, Teri Hatcher, George Clooney, Sylvester Stallone, Ricardo Montalbán, Bill Paxton, Steve Buscemi, Cheech Marin, Christopher McDonald, Taylor Momsen... yeah and Jessica Alba. Also worth noting that for most of these guys, starring in Spy Kids is a Creator's Oddball since almost all of them are/were known for starring in much more mature content.
- Channel Hop: Kind of. The first three films were released under the Dimension Films name, but the fourth was released by The Weinstein Company. Both companies are owned by the Weinstein brothers (in the case of Dimension, it was originally owned by the Weinstein's former company Miramax Films back when they were owned by Disney, but after the Weinsteins left Disney they took Dimension and made it a TWC banner; Disney later sold off Miramax). The fifth film would be released by Netflix.
- Disabled Character, Disabled Actor: Ricardo Montalbán was actually a wheelchair user when he was acting in the movies. Robert Rodriguez specifically wrote the role for him.
- Follow the Leader: MGM followed Agent Cody Banks, while Cartoon Network followed Codename: Kids Next Door and Universal turned Thunderbirds into this after having sat in Development Hell.
- Franchise Killer: 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. But that didn't stop an animated Netflix series from happening. This has been fully averted however, as in January 2021, it was announced that a reboot of the series is in development with Rodriguez returning to write and direct.
- Playing Against Type: Danny Trejo as a good guy in a kids' movie, Mike Judge of all people as the Big Bad in Spy Kids 2 (and an extremely rare live-action role, to boot) and, of course, Robert Rodriguez was directing lighthearted family films.
- Production Posse: Several of the actors had previously worked with Robert Rodriguez, if that provides any context for the casting:
- Antonio Banderas: Desperado, Four Rooms.
- Danny Trejo: Desperado, From Dusk Till Dawn.
- Salma Hayek: Roadracers, Desperado, From Dusk Till Dawn, and The Faculty.
- Robert Patrick: The Faculty and From Dusk Till Dawn 2: Texas Blood Money.
- Cheech Marin: Desperado, From Dusk Till Dawn.
- Elijah Wood: The Faculty.
- Steve Buscemi: Desperado.
- Sequel Gap: Eight years between Game Over and All the Time in the World. And then twelve years between ATTITW and Armageddon.
- So My Kids Can Watch: Considering many of the principals are best known for making hard-R action films, this is likely a major motivation for the movies being made. Also why Jessica Alba and Joel McHale did the fourth movie.
- Trilogy Creep: It originally announced that the third film would be the last, as the young actors, in particular Alexa Vega were growing out of the roles.
- What Could Have Been:
- Angie Harmon was considered for the role of Ingrid, but her commitments on Law & Order prevented her from participating. Kelly Preston was offered the role, but declined as she'd just given birth.
- According to Robert Rodriguez, the theme park at the beginning of Spy Kids 2 was originally going to be Disneyland, but then the studio informed him that Disney generally doesn't allow films to be shot in their theme parks. Therefore, Six Flags Over Texas in Arlington standing in as a fictional park was used instead.
- Brie Larson and Elizabeth Olsen apparently auditioned for the role of Carmen.
