After entering into a passionate affair with a much younger woman, an unhappily married man resorts to murder as a means of eliminating his wife in director Ira Sachs' period melodrama. Set in the 1940s, Marriage tells the tale of Harry (Chris Cooper) -- a man whose wife, Pat (Patricia Clarkson), only wants sex. Smitten by the beautiful Kay (Rachel McAdams) but ultra-sensitive to his wife's feelings -- so sensitive that he can't stand the thought of breaking her heart -- Harry opts to poison his wife as a means of allowing the marriage to end with her pride still intact. Harry's scheme soon goes horribly awry, however, when after revealing the plan to his best friend, Richard (Pierce Brosnan), Richard too falls in love with the ethereal young beauty and sets into motion a cunning plan all his own. A serpentine tale of murderous deception, Marriage was co-scripted by director Sachs and screenwriter Oren Moverman.
