wait what is Kingdom of the Sun, google is being very vague about it
it was the emperor’s new groove before upper level management at disney completely fucked it over!
it was originally going to be a loose adaptation of the prince and the pauper, kuzco and pacha looked identical and would switch places so kuzco would experience life outside the palace
also yzma was the daughter of a witch doctor and her motivation was to summon an ancient incan god to get rid of the sun and push the world into eternal night because she blamed the sun for the fact that she ages
the llama transformation plot was still in there somewhere i think? i can’t remember exactly what the plot was because it changed so many times and disney is super secretive about what actually happened before they scrapped everything and started it over as the emperor’s new groove BUT if you can get your hands on a copy of a documentary called “The Sweatbox” then it will be super useful!! Kingdom of the Sun was originally going to be a musical and the songs were written by Sting but he only accepted the job on the condition that his wife could film the entire production history
disney owns the rights to the documentary and they’ve never released it officially because most of it is just various animators talking about how the executives at the company were a bunch of assholes who prioritised money over artistic integrity (IIRC they refused to push the release date of KOTS back to further develop the story because they had a licensing agreement with mcdonalds happy meals that they didn’t want to have to cancel and reschedule, which resulted in everything being scrapped and The Emperor’s New Groove being made in just over a year from the tattered remains) but it leaked onto the internet a few years ago, you can download the torrent here if you’re outside the USA… idk if the US is still barred access from kickasstorrents but it’s not THAT hard to find if you just google “the sweatbox torrent”
but anyway yes it was originally planned as an epic musical along the lines of The Lion King (you can hear the villain song that Yzma was originally going to sing here) but it got watered down into the buddy comedy that it is today which is why i really don’t like it because the original concept seemed so cool and original and it turned into like… south american toy story lol
i have a VERY small tag about it on my main blog about it as well
