I think it is more marketable to everyone if he is
not black:
Most white families will write the movie off if there are all black people in iterplexed.
In fact, most shows on television where the cast is all black white people will flip right past it (remember the black people hour on UPN?), and most movies with all black people they refuse to watch. They call them black shows or black movies because they think only black people should watch it. Strangely enough we are expected to watch movies and shows with all white people (Friends for example). So if Disney makes a movie like that they are risking it to flop in the box office.
If they add a white prince, they are risking a few racist parents avoiding it, but they are more likely to get black
and white people who want to watch it. This is probably the better choice right now. They need to move away from all white people, and this is their first step and its a good one.
There is a growing number of IRR who have biracial children who would love to see a movie with a black princess and a white prince (and we know there are at least 20 more years before they even consider a black prince and a white girl so we should take what we can get)
so this could turn out great.
I am still offended however that of all the princess Disney movies, they can't even consider an African princess? That just doesn't make sense to me.
There are more black princesses in the world than white, so I don't understand how they want to act like its the other way around.
