A few months ago, director Daniel Goldstein and scenic designer Dane Laffrey went prowling around the Cobble Hill section of Brooklyn, peering in windows like a pair of peeping Toms. They deliberately set out at night so they could see inside the elegant townhouses in the tony neighborhood, which is known as much for its opulence as for its family-friendly environment. They tried to keep a low profile as they cased the area and stole glimpses of the rarefied artwork and the exquisite furnishings inside other people’s homes.
As suspicious as it might have appeared, the surveillance was all in the name of research for “God of Carnage,’’ Yasmina Reza’s popular comedy that begins a monthlong run tonight at the Huntington Theatre Company - one week before Roman Polanski’s movie adaptation, “Carnage,’’ opens here.
