I think Nancy was played recently in the West End by a biracial black/white woman. I know what you are getting at but sometimes I think that people should be a bit open to other races taking on parts that have traditionally been played by white people.
The majority of plays that we know today white people have been cast in the leading roles.
In schools today some black talented children who are good at drama maybe missing out on playing some roles because of their colour.
It bothered me last year that not a single black person got through to try for Maria.
I think it is good that black people have made it to the heats this year.

I also thought that Brandy's remake of Cinderella was a great idea.
