As we all know, The Little Mermaid is based on a fairy tale by Hans Christian Anderson. In it, the prince falls in love with the princess of a neighbouring kingdom. So could Ursula’s human disguise be based on her?
Edit: inIn the original fairy tale, the Princeprince thinks the princess is the one who saved him. In the Disney film, Vanessa tricks Prince Eric into thinking SHEshe saved him.
