i see one tiny problem disney might have with this in the parks Ariel is white in the live action movie she won't be white, good luck to parents and cast members try to explain that to a kid and also the kid might ask the lady from the fog movie which was disney's first movie about that race and last hand draw movie. So disney was like i know we do have a black princes but now whatever we can make a princes any color we want, yay money.
Why would a kid ask Tiana about Ariel's race or anyone's race for that matter? Were there a lot of reports of kids asking Cinderella about race after seeing the Brandy version? Why assume it is a "yay money" grab, rather than selecting the best person for the part? Changing one princess does not mean they are going to change them all...
