MGM's The Trial of Mary Dugan was based on the popular stage play by Bayard Vellier, previously filmed as a Norma Shearer vehicle in 1929. This time, Laraine Day is cast as Mary Dugan, a young stenographer who is falsely accused of murdering her philandering employer Edgar Wayne (Tom Conway). In the course of her trial, Mary falls in love with her attorney Jimmy Blake (Robert Young). The original
Trial of Mary Dugan was highlighted by the heartfelt testimony of the tarnished heroine, who recounted a life of shame and degradation endured on behalf of her impoverished law-student brother. Thanks to the tightened censorial restrictions of 1941, Mary Dugan's checkered past is eliminated, leaving the viewer with just another courtroom melodrama. ~ Hal Erickson, All Movie Guide
