Andy Quiroga is one of our dependably elastic character actors, excelling in invariably smallish parts such as the homoerotic hustler in Mangrove Creative Collective's Paradise Motel and the volcanic father in Alliance Theatre Lab's Off Center of Nowhere. But this year's Frankie and Johnny in the Clair de Lune provided him with the meatiest role he's enjoyed in years, a riveting reminder he has the magnetism to carry a show. In the rebranded Alliance Theatre's comeback show, written by Terrence McNally, he played Johnny, the male part of a one-night stand that might become something more, if only the lonely waitress would just acquiesce to his plans for their future. Quiroga displayed a rare and, for this role, necessary ability to act creepy and sincere at the same time. At various points in the play's two extended acts, he was as clingy as plastic wrap, as chivalrous as a knight, and as emotionally naked as a support-group member. Until the very end, we didn't know exactly what to think of him, which means he was doing his job exactly right.
