Plays about passion are profuse and easy: heterosexual or homosexual, interracial or senescent, kinky or chaste. What is difficult and rare is a play about affection, which is what Carrie Hamilton and Carol Burnett's Hollywood Arms is. Authentic affection: not syrupy or sentimental, posturing or feel-good-ish, gussied up for theatrical effect. Hollywood Arms is about real people who fight or let one another down, jab and jeer, needle and explode, but also, when need be, help people who are sarcastic or pathetic failures, impoverished and disappointed.
