A few years ago, Pixar had explored a version of The Frog Prince set in gangland Chicago. John Lasseter wanted to switch the locale to New Orleans, a city he loves, but the project was eventually shelved. Meanwhile Disney had explored various versions of The Frog Prince going all the way back to the time of Beauty and the Beast. In 2006, Disney bought the rights to a book called The Frog Princess, which was the fairy tale with a twist: when the Princess kissed the frog, she turned into a frog as well.
