During World War II (when this film was made) Anna May Wong went out of her way to clarify that she was of Chinese heritage and not Japanese. This included regularly supporting and doing volunteer work for organizations raising funds for Chinese resistance to the Japanese invasion and domination of China.
Blonde Mae Clarke who plays the singer sympathetic to the Chinese resistance's cause, had both of the best known roles in the same year. In 1931, she was featured as both the gun moll in whose face James Cagney mashed half a grapefruit in L'ennemi public (1931), and as the bride of Victor Frankenstein, who was terrorized by the monster in the original Frankenstein (1931).
During World War II, with the negative attitude toward Asians, accomplished Chinese-American Hollywood star Anna May Wong was reduced to making only two feature films, including this one, both for the poverty row PRC (Producers Releasing Corporation).
This was one of several war-era films in which Harold Huber was cast as an Asian, even though he was of Russian-Jewish descent.
Last starring role for Anna May Wong and her last picture for seven years until Choc en retour (1949), her penultimate feature film.
