In the Denver Center Theatre Company's Lobby Hero, Bill Christ played a cop who seemed to have no insides, a kind of parody of a cop. He mouthed the heroic, tough-guy lines you so often hear in television dramas, bullying and prevaricating, and fluidly took on whatever persona suited his needs at any particular moment. Christ's character was both goofy and vicious, but he did have his own code of honor that he believed in with all his heart -- until that code of honor became inconvenient. The brilliance of Christ's performance was his ability to give this squirrelly character a real core, showing the mix of insecurity and arrogance that animated him. It was a stellar performance in a bright spot among this season's theatrical offerings.
