Strangest Disney Concept Art:

Starting off is Official Concept art of Cars, McQueen had a nightmare scene where he sneezed out his Engine, which would put to bed the Homunculus humanoid Cars theory.

Early Concept art for Moana had Maui be bald or have a light buzz cut to match the hairstyle of his Voice actor Dwyane the Rock Johnson.

In Early Concept art for Pocahontas she was supposed to be depicted as much younger around 10 or 12. When the higher ups at Disney wanted it to be a romance movie, they had to redesign the character to be older.

Before James Woods was casted as Hades in Hercules, early concept art depicted Jack Nicholas as Hades and had a design based off of his caricature.

Early Designs for Wall-E had him looking much more robotic with less Pareidolia which s the concept of seeing human features in inanimate objects.

The Original Gaston was going to be much more slender and posh, he was later changed into a brute

And last but not least: Early concepts of Woody and Buzz had much more cartoony proportions, Woody was supposed to be a ventriloquist dummy.
