A macabre comedy of manners with the sting of dry ice, this 2007 ensemble piece captures the social climate of America in the late 40s, when a new anxiety and restlessness began to undermine the postwar optimism. A New York businessman (Chris Cooper) becomes smitten with a young widow (Rachel McAdams) and decides to bump off his devoted wife (Patricia Clarkson). Pierce Brosnan enlivens the convoluted story as Cooper's best friend, who also serves as the narrator. Ira Sachs directed a screenplay he cowrote with Oren Moverman (I'm Not There). PG-13, 90 min.
