This film is a revised version of a 1930 film of the same title which is now lost. It was based on a 1924 stage musical that itself was completely revised from the first version that flopped on the road in 1923. Producer Harry Frazee gutted the original, put in mostly new songs and had a hit in Chicago. The two songs that became hit tunes were brand new - "I Want to Be Happy" and "Tea for Two." The original source of all of this was a farcical Broadway play of 1919, called "My Lady Friends," by Frank Mandel.
In this version, young Eve Arden plays the character of Winnie, but in the Doris Day remake Tea for Two (1950), she plays Pauline.
Though Nanette is portrayed as being a young girl/woman in dress, manner, and other characters' references to her (example: her uncle refers to her as his "little niece" on the phone), Anna Neagle, who plays Nanette, was somewhere around 36 years old during the making of this film.
When Tom is following William and Nanette in a cab, he tells the cabbie to turn off the radio, which is broadcasting a horse race. The cabbie objects because he wants to know what happens to Samson and Delilah. Nine years later, Victor Mature would star in Samson and Delilah (1949).
