In my teens, I saw a community theatre production of Fiddler on the Roof with a Black Tevye. Tevye's wife and daughters were cast white. The actor walked on stage, opened his mouth, said "A fiddler on the roof..." and that was that. It was a great actor playing a role that most companies would have denied him. It really opened my eyes to what is possible when you let an actor act, beyond what is considered customary or inherent to the script.
