My Son, the Hero was a rare comedy from the PRC studio mills-and rarer still, it was directed by melodrama specialist Edgar G. Ulmer. Roscoe Karns plays a third-rate fight manager misleadingly known as Big Time. Justifiably proud of his war-correspondent son Michael (Joseph Allen Jr.), Big Time tries to measure up to his son's accomplishments by writing letters to the boy, claiming to be a wealthy businessman. When Michael comes home on furlough, Big Time panics, worrying that he'll be exposed as a fraud. But he hasn't taken into consideration his golden-hearted ex-wife Gerty (Patsy Kelly) and punchdrunk prizefighter Kid Slug (Maxie Rosenbloom), who help Big Time come off as a hero in the eyes of his son. My Son, the Hero represented Patsy Kelly's last film appearance until her comeback role in Please Don't Eat the Daisies (1960).
