But what about, say, Les Miserables, a wholly fictional story based on a backdrop of historical fact. Or The Phantom of the Opera, set at a specific time in Paris yet a gothic fantasy story (of course they don't cast all French people in either of those now do they). In the world of business the answer is simple: hire the best man, yet in theatre it becomes something else entirely. I think we're all agreed that if ethnicity plays a part in the plot, ie. Miss Saigon, Hairpsray, then obviously casting should be according to character, but what about Evita then? It's clearly a western musical and a rock opera, but ethnicity isn't part of the story as everyone is Argentinian, so is that ok? It's always gonna be a tricky subject. Take, say, B&tB, if the original character is a white girl with brown hair, should the on-stage version be the same to be faithful to the original or is it irrelevent? So many questions that will never have an answer and will rage on forever.
