The group, which was founded in 1950 -- a time when gay men referred to themselves as "temperamentals" in a manner not unlike men in Oscar Wilde's late Victorian England who wore green carnations to signal each other -- was organized by Harry Hay (Thomas Jay Ryan), a card-carrying member of the Communist Party, and Rudi Gernreich (Michael Urie), a Viennese refugee working in Hollywood as a sketch designer for Edith Head while befriending closeted director Vincente Minnelli (Tom Beckett). (Gernreich would much later gain worldwide fame for designing the topless bikini.)
Accustomed to championing unpopular causes, Hay encouraged new lover Gernreich to join him in recruiting other "temperamental" men ready to fight for equal rights in a repressive environment. The pair quickly convinced Bob Hull (Matthew Schneck) and his significant other, Chuck Rowland (Beckett again), to sign on. The society then began to build significantly in 1952, when newer member Dale Jennings (Sam Breslin Wright) was arrested in a public toilet for lewdness and decided to identify himself at his trial as homosexual and maintain he was an entrapment victim.
The case is dismissed due to a hung jury, Jennings becomes a community hero, and the society gathers more members, even as Hay and Gernreich have their personal differences over Gernreich's fashion career and Hay is summoned to appear before the House Un-American Activities Committee. The attending notoriety exacerbates intramural Mattachine conflicts so that by 1953 the four initial creators resign == and the rest is reclaimed gay history.
The play might have devolved into little more than a Powerpoint lecture had Marans not been so ingenious about constructing his work in short scenes during which Hay and Gernreich play out their deep devotion to each other, while the Mattachine movement gains traction and what seem like scores of peripheral parades through their lives and through their unceasing determination to legitimize themselves and their brothers and sisters.
Part of Marans' ingenuity is having four of the five actors assume multiple parts on a dime, including sunbathing (and topless) men, ladies in hats representing some of the women in Hay's life, and assorted lawyers, policemen, and even HUAC interrogators. While Ryan commands as the usually serious Hay, the others -- even Urie, playing Gernreich with a cunning Austrian accent -- jump through the colorful character hoops Marans has devised. Beckett, Schneck and Wright are particularly effective as, respectively, flamboyant Chuck, reticent Bob, and tough-guy Jennings.
Moreover, the requirements of the play's lickety-split pace are met by director Jonathan Silverstein, who also makes the most of a set designed by Clint Ramos on what must have been an extremely short shoestring. The audience is kept attentive and frequently laughing at the characters' antics, while several metal chairs are moved about under six hanging bulbs in a small room where mullioned windows behind the playing area have been blacked out.
