"Professional Sweetheart" was Ginger Rogers' first film for RKO and - ironically, since so much of the plot revolves around getting Rogers' character to sign a radio contract - she had not yet signed a long-term contract with RKO when she made this film. She would sign a contract with the studio later in the year, just before making Flying Down to Rio (1933), her first film with Fred Astaire.
An early mention of television by the radio announcer in this film from 1933.
While Glory (Ginger Rogers) spends a lot of the film in her scanty underwear, she never dons the black lingerie she insists be bought for her, although a publicity shot is seen in the image section. Apparently this was too daring even in Pre-Code days.
While commercial TV in the US didn't begin until a dozen years after the release of this film, the film's reference is to early demonstrations that were taking place from the mid 1920s.
Rogers' singing voice was dubbed by Etta Moten.
