Ursula
Ursula was based on Glenn Milstead’s famous drag queen persona, Divine. This might be surprising since Glenn wasn’t involved in the Disney project at all. Howard Ashman, who’s known Divine, composed the music for The Little Mermaid and wound up being a producer for the movie. Unfortunately, Divine passed away before being able to watch the movie. Friends of the late drag queen have said Divine would have adored the character.
Shrek
It seems like Shrek is a worldwide favorite when it comes to famous fictional characters. Well, he was based on the Russian-French wrestler, Maurice Tillet. He had a rather distinct appearance due to his condition, acromegaly, which resulted in bone overgrowth. DreamWorks hasn’t openly admitted to the likeness between the two, but just looking at pictures of them side-by-side draws a lot of speculation. Additionally, Tillet was a very kind and gentle man – another similarity to Shrek.
