* ActingForTwo: Creator/GeorgeLopez plays several roles in the film. In addition to the obvious Mr. Electricidad and Mr. Electric roles, his voice was deepened for Tobor and pitched up for the Ice King. In the Latin Spanish dub, Humberto Vélez did exactly the same. In the 3-D version of the movie, [[https://youtu.be/dNX-RBL7cQQ?t=60 he also voices an intro sequence that instructs the audience to put their 3-D glasses on.]]

* BasedOnADream: Specifically, those of director Creator/RobertRodriguez's son Racer, as well as some drawings Racer had done.
* KidsMealToy: UsefulNotes/McDonalds released a set of eight Happy Meal toys, including action figures of the titular duo, 3D glasses, and a dream journal.
* WhatCouldHaveBeen: Around the same time that she auditioned to play Lilly in ''Series/HannahMontana'', a young Music/MileyCyrus auditioned for the role of Lavagirl ([[WordOfGod as she states]] in her autobiography, ''Miles To Go''). Although she did not get the part, she met and became close friends with Taylor Lautner, a friendship that's lasted to this day.
* WrittenForMyKids: Rodriguez wrote the film based on his son's imagined and dreamed stories.
