Different Stages closes its 2015-2016 season with Ronald Harwood’s The Dresser. ‘Sir’, the last of the great but dying breed of English actor-managers, is struggling to keep a grip on his sanity and complete his 227th performance of King Lear. Despite most of the country’s actors being in uniform in war-torn Britain and bombs destroying theaters, the show must go on. Ensuring that it does is Norman, Sir’s devoted dresser, who for sixteen years has been there to fix his wig, massage his ego, remind him of his opening lines, and provide the sound effects in the storm scene.
