This was a surprise hit for Paramount. A quickie, it was shot in a mere 15 days and its success immeasurably helped director John Cromwell's career.
Loosely based on the career of New York attorney William Fallon.
Bill gives the speakeasy bartender the real phone number at the time for the New York Police Department headquarters - SPring 3100.
When Bill is talking to Irene in the speakeasy, he mentions men who built themselves up to look like the Woolworth Building - which was the tallest building in the world when this film was made. It was soon to be surpassed, in quick succession, by 40 Wall Street, the Chrysler Building, and the Empire State Building in 1930 to 1931.
Third of six films Kay Francis and William Powell made together that were released from 1930 to 1932.
