William Powell had a mustache for the entire length of his career, but he shaved it off for this movie for the sequences in which his character poses as a woman. (This is not entirely accurate. He also shaved it off for the prison scenes in Shadow of the Law (1930).)
The film was remarkably well received by critics, who generally viewed it as one of the best Myrna Loy-William Powell pairings to that point.
"It's Delightful to Be Married", sung by William Powell in the beginning, also is featured in The Great Ziegfeld (1936), a film also starring Powell, as the song Anna Held learns after arriving in America.
The plot, which hinges on divorce, struck quite close to home for Myrna Loy; she was in the process of finalizing her divorce from Arthur Hornblow Jr. during production.
