* ExecutiveMeddling: The movie was intended to be an erotic horror flick about a cartoonist who had sex with a sexy cartoon woman he created named Debbie Dallas and is now the father of a half-human, half-cartoon girl who considers herself a freak and goes on a rampage against the man who spawned her. Sadly, Frank Mancuso Jr. and Kim Basinger nixed that at the last minute to make it more kid-friendly (though it really doesn't come off that way) and into the complete and total bomb we know it as.
* HeyItsThatGuy: Milton Knight worked on this film, as background character designer. He would later be known for working on ''WesternAnimation/AdventuresOfSonicTheHedgehog''. His website has character designs for the film, while others that didn't get into the finished product.
** Who knew that Jack Deebs was also [[Film/{{Excalibur}} Uther Pendragon]], father of King Arthur?
* HeyItsThatVoice: Lonette is [[CandiMilo Sweetie Pie]] (the pink, female Tweety Bird) on ''WesternAnimation/TinyToonAdventures''. In fact, ''Tiny Toon Adventures'' and this movie were Candi Milo's breakout roles.
** As for Nails the Spider, he's voiced by CharlieAdler, the same guy who brought you [[WesternAnimation/RockosModernLife Mr. and Mrs. Bighead]], [[WesternAnimation/CowAndChicken The Red Guy who goes by many names that refer to his rear end]], [[WesternAnimation/IAmWeasel I.R. Baboon]], [[WesternAnimation/TinyToonAdventures Buster Bunny]] (up until the last season), and Ickis from ''WesternAnimation/AaahhRealMonsters''.
** And the voice of both Dr. Vincent Whiskers and the super hero Jack is MauriceLaMarche, also known for [[WesternAnimation/{{Animaniacs}} The]] [[WesternAnimation/PinkyAndTheBrain Brain]], [[WesternAnimation/TheRealGhostbusters Egon Spengler]], [[WesternAnimation/InspectorGadget Chief Quimby]], [[WesternAnimation/CodenameKidsNextDoor Father]], [[WesternAnimation/TinyToonAdventures Dizzy Devil]], [[WesternAnimation/{{Futurama}} Kif Kroker]], and [[VideoGame/BatmanArkhamCity Mr. Freeze]].
* MeanCharacterNiceActor: Kim Basinger plays the BigBad but was part of the ExecutiveMeddling out of a desire to be able to show Cool World in hospitals for sick children.
* MidDevelopmentGenreShift: This was originally intended to be an erotic horror film, but [[ExecutiveMeddling Frank Mancuso Jr.]] didn't want to make a horror movie, and [[WagTheDirector Kim Basinger]] wanted something more family-friendly.
* WhatCouldHaveBeen: The original horror concept (in which Jack has sex with Holli [who was actually named Debbie Dallas, after the infamous 1970s porno, ''Debbie Does Dallas''] and Holli has a half-cartoon, half-human daughter who sees herself as a freak and plots to kill her parents) would have made a '''much''' better movie than a Roger Rabbit ripoff we have now. Blame [[ExecutiveMeddling Frank Mancuso Jr. and Kim Basinger]] [[ExecutiveMeddling for screwing it up]].
** Originally, CandiMilo wasn't supposed to be the voice of Lonette. She was only there as a line-feeder for the other actors, but she was put in after the producers saw that she was great with doing voices and acting.
** Brad Pitt and Drew Barrymore were Ralph Bakshi's original choices for the roles of Deebs and Holli.
