http://www.cbc.ca/q/episodes/ Look for the Aug 11 episode of this program.
It is about whether it is appropriate to stage operas like Mikado and Madam Butterfly which seems quaint and outdated with stereotype Asians and old attitudes about the exotic East.
Are these white actors displacing positions that should be taken by Asian actors?
Can Asian or African American actors take on roles that are not of their ethnic appearance?
Can an older actor take on the role of a young character while obviously not appearing young?
Is appearance a major part in performance art? So much so that it trumps all other considerations?
Then there is the question of dealing with classics that no longer reflect current values of race, gender, and sexuality sensitivities.
Should terms like "yellow face" in Mikado or negro in Mark Twain's works be changed or deleted or should they remain as they are?
It is easy to forget how far we have changed in our attitudes and how different our surroundings are from a century ago when some of these literary works were created.
Seeing the works as they are gives us a glimpse of a world where people seldom travel, do not meet anyone other than their own ethnicity, and anything foreign is exotic, exciting, and full of adventure.
