Doing It for the Art: Chuck Jones once commented that only Disney would make an animated film about one hundred and one dalmatians: "if I had tried to make One Dog Named Spot for Leon Schlesinger, he would not let me do it. Spots cost money."
Edited for Syndication: Disney Junior's reruns of the animated series cut out numerous jokes and one-liners.
Ivy (Cruella's niece) is Ashley Q. (While Anita's niece, Amber, is Ashley B.)
Whizzer is the library kid
Mooch is Mundy
Meanwhile, from a different series, Jasper and Horace are Lenny and Squiggy, respectively.
Recycled Script: The premise of Thunderbolt learning to be a real hero as seen in Patch's London Adventure first showed up in an episode of the TV series "Watch for Falling Idols".
What Could Have Been: Cruella DeVille almost became the villain in The Rescuers. It shows, as the villain of the movie is very similar, both in personality and looks.
