In the beginning of the film, Pons' character escapes her wedding in a non-supercharged 1936 Cord 810 convertible coupe. The Indiana-made car, which cost about $3,700 was rare even when new and exotic enough to look like it belonged in the movie which begins set in France. In just "good" condition in 2021, an example of this car is worth well over $100,000.

According to studio records, this film returned a profit to RKO Radio Pictures of just over $100,000, making it one of the studio's most successful releases of 1936.
This film was part of a concerted effort to develop operatic soprano Lily Pons into an RKO star, as M-G-M had done with Jeanette MacDonald. After several starring roles failed to "put Pons over," the project was abandoned, and she returned to her live operatic career.
Richard Carle is listed by a modern source as an actor in this film, but he was not seen in the print.
