Howard Sherman: “The convention of the fourth wall is deeply ingrained in most regular theatregoers … But when such techniques [for breaking it] are deployed intentionally before, during and after a performance, the effect can be magical. … There needn’t even be a show in performance for the effect of bringing audiences on stage to have an impact. Even in smaller spaces, let alone iconic ones, allowing patrons to stand where the actors perform creates an inversion that can be highly affecting.”
