Who'd ever think the inside world of a small real estate office would contain such colorful dialogue as: "Ever take a dump that makes you feel you slept for 12 hours?" Leave it to David Mamet to transform the seemingly mundane world of selling property into a seething stew of deceit, desperation, and verbal violence. This production of Mamet's Tony Award-winning play, depicting ruthless salesmen doing absolutely anything to seal the deal, is sharply realized by the Actors Theatre of San Francisco. Director Jennifer Welch does not let the pace or tension lag in this 90-minute racehorse that starts out like a great caper film and ends as a tense whodunit. Despite an unremarkable set and a few cast members who can't naturalize Mamet's choppy dialogue, this Pulitzer Prize-winning script is practically foolproof. As real estate agents, Andre Esterlis is deliciously sinister and Aaron Murphy provides the great comic relief of an innocent in a cutthroat world. Even after two decades of stage productions and a Hollywood film adaptation, it still feels razor-sharp and brutally honest.
