Joan Perry plays the title role in Columbia's Counterfeit Lady. She is cast as Phyllis, a country lass with a rare talent for larceny. Managing to steal a $37,000 diamond from a swank New York jewelry shop, Phyllis is pursued by private detective Johnny (Ralph Bellamy), and by a gang of professional thieves who play for keeps. Johnny rescues the heroine from the villains, whereupon she instantly reforms in order to permit a climactic romantic clinch. So well does Joan Perry pull off the leading role in Counterfeit Lady that it seems a shame she retired from acting after becoming the wife of Columbia prexy Harry Cohn. ~ Hal Erickson, All Movie Guide
