Burnsy I understand what you're thinking. It is Germany after all and I don't believe that there were any minorities around in that country in that time (not saying that there weren't, just not any present in the book). However, considering it is theater I'm just glad for once that ethnicity didn't rule out someone's obvious talent. I don't mean to sound harsh in the way I state this but I've always seen shows where there was a bunch of white people, maybe some african americans here and there and one asian person...maybe. Audiences nowadays have come to expect African Americans in lead roles (i.e. Pearl Bailey in Dolly, Toni Braxton in B&B) It's just nice to see now that other ethnicities could and would possibly have an equal chance of playing the next Belle or the next Ariel etc.
