If I recall correctly, he's playing 16 characters. I've seen Macbeth a number of times and, granted its not my favorite Shakespeare by far, I can barely remember the names of 16 characters once you get past the leads...
I'm glad you thought it was crystal clear. Don't say it's "impossible," because your claim becomes very easily falsifiable. .
Words don't deserve that kind of malarkey. They're innocent, neutral, precise, standing for this, describing that, meaning the other, so if you look after them you can build bridges across incomprehension and chaos. But when they get their corners knocked off, they're no good anymore…I don't think writers are sacred, but words are. They deserve respect. If you get the right ones in the right order, you can nudge the world a little.
