It would be nice to see American actors get a chance to be in this, since it'll surely run for years unlike most plays. That said, I wouldn't mind seeing Noma Dumezweni come with it- she was excellent in A Human Being Died That Night at BAM last year.
I am a firm believer in serendipity- all the random pieces coming together in one wonderful moment, when suddenly you see what their purpose was all along.
