When most people think of Shakespeare’s The Merchant of Venice, it's Shylock who springs to mind, not the titular merchant. As a Jew in a Christian city-state, Shylock is an outsider; as a moneylender in an economy that reviles usury, he’s a pariah. Director Arin Arbus has chosen John Douglas Thompson, one of the most accomplished classical actors of his generation, as Shylock in her modern-dress production at Theatre for a New Audience (TFANA). Thompson, reportedly the first Black actor to play Shylock professionally in New York, finds music even in the most acidic passages of the Bard’s rhetoric; his nuanced performance explodes at crucial points, with moral indignation outstripping self-pity.
