The movie, which is due around Christmas this year, is set in the "jazz age" in New Orleans. Oprah is the voice of Tiana's mother. Anika Noni Rose says of Tiana: "Not only is she the first black princess, she's the first American princess. We've never had an American princess. So, the scope and the significance is larger than people even realize." Uh, Pocahontas was American, though, right?
