Fishburne has the air of wisdom of someone who, having undertaken deep self-investigation, is eager to share his findings. (The restrained undulating projections designed by Elaine J. McCarthy have a light-behind-the-eyelids feel, evoking memory and contemplation.) To the question of legacy, Fishburne seems to say: It’s not the stage and screen roles that matter, but his powers of perception — of others and of himself. It’s a skill you don’t have to be a movie star to perfect.
