* CrossDressingVoices: Although Jerry the Mouse is clearly supposed to be a male, he was voiced by Sara Berner.
* WhatCouldHaveBeen: Originally, instead of [[WesternAnimation/TomAndJerry Jerry Mouse]], the character who was going to dance with Creator/GeneKelly was ''WesternAnimation/MickeyMouse''. Reportedly, Creator/WaltDisney even agreed to loan Mickey out, but big brother Roy said no. Walt Disney Studios was deep in debt after UsefulNotes/WorldWarII, and they had no business making animation for third parties until they were out of the woods.
