In Maho Mushi, when Timmy and Vickie scream out their battle cries, "Miyazaki!" and "Kurosawa!", it is in reference to Japanese animation director Hayao Miyazaki and the Japanese film-maker, Akira Kurosawa.
As Timmy, Cosmo, and Wanda fly through the void filled with televisions, various images that they pass on the television screens are pictures of The Fairly OddParents (2001) production staff. These images include series creator Butch Hartman, director Bob Hoynes, co-writer of "Channel Chasers" Steve Marmel, Tara Strong (Timmy Turner), Susanne Blakeslee (Wanda), Daran Norris (Cosmo), Grey Griffin (Vicky the babysitter), and Jim Ward (Chet Ubetcha), among others.
This is the first Nickelodeon project to feature Alec Baldwin. His next one is Dennis in The SpongeBob SquarePants Movie (2004) which came out 5 months later after this episodes debut.
