Filmed some 18 months before its release, Conflict is one of two melodramas in which Humphrey Bogart self-consciously portrayed a wife murderer (the other was The Two Mrs. Carrolls). Bogie plays unhappily married Richard Mason, who concocts a meticulous scheme to kill his shrewish wife, Kathryn (Rose Hobart), so that he'll be free to marry her sister, Evelyn (Alexis Smith). Alas, Mason inadvertently tips his hand to family friend Dr. Mark Hamilton (Sydney Greenstreet).
