Preachy moralizing on a downbeat subject, "An Act of Murder" is somewhat redeemed by outstanding performances by Frederic March and his actress wife, Florence Eldridge. A strict judge is faced with a moral dilemma, when his wife of 20 years is struck with a fatal disease that is incurable and increasingly painful. Most of the film's running time deals with the judge's home and work life, his daughter's relationship with an attorney the judge dislikes, and visits to a doctor, who is a personal friend of the couple.
Movies about terminal illness are often cloying TV fodder and difficult to endure; few are entertaining and tolerable like "Dark Victory," in which Bette Davis overcame a dire prognosis by sheer force of her personality. Directed by Michael Gordon and adapted from a novel by Ernst Lothar, this low-budget film does avoid maudlin moments and is no tearjerker. Eldridge as Catherine Cooke faces her crisis with courage and dignity, even while her symptoms worsen and her health declines. March's Judge Calvin Cooke stoically witnesses his wife's pain and addresses the imminent loss of his partner without self pity. However, the story reaches tedious sermonizing during a climactic courtroom scene. Edmund O'Brien, who plays the daughter's improbable love interest, steps into the court proceedings to make a point, after which a judge, portrayed by John McIntire, delivers a lesson about heart in the law, and March closes the film by declaring himself a changed man.
To say that "An Act of Murder" is entertaining is a bit of a stretch given the subject matter. To say that the film's moral teaching is groundbreaking would be untrue for most people. However, the sensitive portrayal of a loving couple facing loss after twenty years of marriage acted out by a loving couple after twenty years of their own marriage is reason enough to endure the sermonizing.
