Based on a successful stage play, The Remarkable Mr. Pennypacker loses in this adaptation to film by becoming more serious than an all-out farce. The setting is the end of the 1800s and the intrepid Pennypacker (Clifton Webb) runs a sausage company with two thriving plants in Philadelphia and Harrisburg. He shuttles back and forth between the cities and with equal aplomb, between two households. He maintains one wife (Dorothy McGuire) and eight children in one city, and another wife (Jill St. John) and nine children in the other. When one of the Mrs. Pennypackers finds out about his deception, the unruffled businessman sees no reason for her emotional reaction. Victorian inhibitions and rigidities are set against ultra-modern thinking, embodied in the people the bigamist admires -- like Darwin, the feminists (!), and free-thinkers.
