I ask this all just because of curiosity, but I really hope it does not come across as racist as that is not my intent.
Are there any good black actors who would fit the role?
Isn't that a bit like asking "are there any good black actors"? There is absolutely nothing about the part that requires the "special talents" (whatever they may be) of Whitey to play it.
For that matter there's nothing about the part that requires a man to play it either.
