”You can win. And all you have to do is shut up,” hisses Julie White’s manipulative Hollywood agent to her closeted movie-star client (Tom Everett Scott) in Douglas Carter Beane’s sly, sharply written satire. But as the actor vacillates between big-screen success and a burgeoning relationship with a sensitive professional gigolo (Johnny Galecki), what he wants to ”win” becomes the question. That the answer leaves a bittersweet aftertaste is no matter. It’s White’s frenetic Tony-worthy performance that turns The Little Dog Laughed into a real winner.
