This film was originally completed as a musical, but due to audience interest in such film waning in the U.S., all of those numbers were cut in the U.S. & UK releases, but left intact for other countries. A print of the U.S. version has been preserved by the Library of Congress.
It is interesting to note that in one scene the characters played by Billy House and Tyrell Davis are discussing Toto's mental state while using a "pissoir", or public urinal, on a street in Paris. At the time of this film the city had over 1,200 such structures.
When Florine and Fifi encounter each other in Toto's apartment, he introduces them respectively as his 'night nurse' and his 'day nurse' and Fifi threatens Florine with the line "I'll 'night nurse' you!" Joan Blondell, who plays Fifi, would go on to play a day nurse in the film Night Nurse (1931). Coincidentally, her co-star in Night Nurse is Frank Fay's (Toto) then wife, Barbara Stanwyck.
Diane's player piano is a Steinway XR Duo-Art Reproducing Grand. In 2018, these pianos, fully restored, can fetch $50,000 or more.
