I was very moved by that play once again when the Royal Shakespeare Company did a production that toured the cathedrals of England. Then they took it to Poland and performed it in the cathedrals there, too. The actors said it changed their lives. Officials wept; they were speechless after the play, and everyone knew why. It was because they had to enforce the kind of repression the play was attacking. That made me prouder than anything I ever did in my life. The mission of the theater, after all, is to change, to raise the consciousness of people to their human possibilities.
