Conflict (movie, 1945)

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).
