Horton Hears a Who!/Trivia


 * Development Hell: Blue Sky reported to have the rights to Horton Hatches The Egg, but that was years ago, and so far nothing has come of it.
 * Hey, It's That Voice!: In the 1970 special, both Horton and the narrator are Captain Hook, and the Kangaroo is Granny (among many, many others).
 * Shout-Out: Several in The Movie to various Dr. Seuss works.
 * One Who has a blue hat similar to the one worn by The Cat in the Hat, as well as a few of The Cat's mannerisms (including a smaller version of himself underneath his hat).
 * The Mayor and his family eat Green Eggs and Ham for breakfast.
 * The city council seems to consist of Grinches.
 * Rudy's imaginary clover friend is named "Thiddwick", a refrence to Thiddwick the Moose
 * The Mayor has a red fish as a pet, possibly a refrence to One Fish Two Fish Red Fish Blue Fish.
 * One of the portraits of past mayors was himself (specifically, the one of Ned's father)!
 * The Other Darrin: The 1970 special is very inconsistent in voicing background characters. This is most notable in the "Mrs. Toucanella" number, where the birds seem to have different voices every line.
