Dressed in navy slacks and a white shirt, and wearing her hair pulled back in a ponytail, Smith doesn't mimic voices so much as she reproduces the speech patterns and body language of the interviewees, who are identified by titles projected on the back wall of the set.
The way she does this is as fascinating as her characters' revelations (from the metaphorical resonance of a physicist explaining how flaws in the reflecting mirror of a telescope can create 'a circle of confusion,' to an angry black teen-ager whose proof of a Jewish conspiracy is that New York police cars are the same colors as the Israeli flag).
