I thought the Princess and the Frog was not based on the traditional Grimm's fairytale "The Frog Prince" - the one where the Princess loses her golden ball and the frog gets it back for her, but on another book called "The Frog Princess."
My elder daughter and I like the film, but reading this thread has really made me consider it from another viewpoint. I like the story, but I think Disney decided to introduce a black princess to its line and found a story to justify that. Why does having a black Princess need justification? It's almost giving the message "Hey, only white girls are real princesses, but look, you black girls can be one too, sort of, aren't you lucky."
I take the point most well known fairytales are european in origin. Well, Disney has a perfect opportunity to take some African stories and make them well known. (And there's a wealth of amazing stories there) Look at Mulan, a little-known Chinese legend, suddenly accesible to everyone(Though there was a bit of a furore over making her too european looking at the time I remember)
I didn't know Prince Nazeem was Brizilian though. I thought he was a prince from an unspecified middle-eastern land who had been cut off from his money because of being lazy, thus looking for a rich american to marry. He definately is an official prince though, rather than just a bloke, even though he doesn't act in a typical "Disney prince" manner.
Thanks for giving me a new way of seeing it. I don't think I'd ever even seen someone who wasn't white until I was in my teens. In fact, I knew nothing of the transatlantic slave-trade/antebellum south/american history/african history until I came across the late, great Octavia E Butler. Her novel, "Kindred" about a modern black woman married to a white man who gets sent back in time to the antebellum south to save a white plantation owner's son time and again is still the best novel I have ever read twenty years after I first read it, and it opened up history to me. Until then I thought history started and finished in Britain.
