Fifty two years ago, Mart Crowley’s The Boys in the Band debuted off-Broadway. The structure was simple, and not unfamiliar to anyone who’d seen a play before: Over the course of an evening, characters gather, get drunk and turn on one another. The groundbreaking difference was that it was a group of gay men doing all that gathering and drinking and lashing out. Now, a new Netflix film adapts the recent Tony-winning revival of the play.
