Ryan McGettigan’s set design was clever. The shelves, drawers and windows of the set were reminiscent of the wall from “Rowan and Martin’s Laugh-In,” minus the colors. A couch would appear out of the wall for the McCarthy living room, a full-sized bed for Frank’s bedroom, another bed in Andrei’s boarding house room, a clerk’s window at city hall or a pier in the fog, all with a quick blackout. ... Credit for the set’s effectiveness should also go to Herrick Goldman’s light design and James Sugg’s sound design.
