I know I had my equivalents in Adrian Lester and Lenny James when I was at drama school. I remember David Harewood doing 'Othello' at the National and Adrian Lester having done Cheek by Jowl's famous 'As You Like It and Company' at the Donmar. Not necessarily performances I saw but just the fact they happened was massively encouraging.
Small natures require despotism to exercise their sinews as great souls thirst for equality to give play to their heart.
