Given how many playwrights live in New York, it’s no surprise that so many dramas take place here. The city’s diversity and extremes, its grandeur and deprivations, make a great muse. One show this year paid a special tribute to Gotham and its strivers. James Lapine’s moving Lincoln Center Theater adaption of Act One, Moss Hart’s famous showbiz autobiography, charted Hart’s journey from his childhood home in the Bronx to cocktail parties with the Manhattan literati to a slot on Broadway marquees. Hungering for a first success during the Depression, the young Moss walks on the Coney Island boardwalk and tries to figure out how to get a piece of the action; Lapine’s sophisticated craft made us feel the town’s cruel social divides as well as the allure of its bright lights — then, now, and forever.
