Deliberate mistake: After the game has entered the real world, and Floop and Minion are there to "save the day", Carmen and Juni throws seven pairs of glasses to them. But afterwords, we see there are only four pairs of glasses on Minion and one pair on Floop, which totals five. (01:11:10)
Spy Kids 3-D: Game Over (2003)
1 deliberate mistake - chronological order
Directed by: Robert Rodriguez
Starring: Antonio Banderas, Carla Gugino, Alexa PenaVega, Alexa Vega, Daryl Sabara
Factual error: Dinky Winks has a branding iron that says 'Dinky' when it faces out, but we should be reading it backwards. When he uses this brand, then it will be backwards.
Juni: I never even got her e-mail address.
Trivia: At the start of the movie, when Juni says, "To finding lost toys", he finds a toy that bears a resemblance to Grandpa in the red armor in the game when he finds "Megalegs".
Question: Why does Carmen answer Juni's question by saying "my feet stink?" Is this a reference to another movie?
Answer: In the 2nd Spy Kids film, when they can read each other's minds, Juni proves it by thinking Carmen's feet stink, at which point she smells her shoe and agrees.
