Mae Clarke was sick during most of the production of The Impatient Maiden (1932) and this film, which were made back-to-back. At the end of this film, she was so sick that her face swelled up and she was having hallucinations. She was able to go for detox treatments in Palm Springs and Pasadena.
The costumes the chorus girls wear in the second number (which ends act one) are reused from the "Happy Feet" number from Der Jazzkönig (1930)
The only film on which Boris Karloff and Busby Berkeley both worked.
Continuing an uncanny yet amusing pattern that seemingly started in 1920 with Der letzte Mohikaner (1920), Boris Karloff here again appears to follow in Bela Lugosi's career footsteps: Bela had already played a nightclub owner, 3 years prior in Prisoners (1929).
