Two things are notable: the only time the studio glamorized Bette Davis (she hated it) and a stupendous Busby Berkeley number where women's belly-buttons are prominently featured (under the code they would disappear for almost 25 years).
The studio made Bette Davis wear a blonde wig and dressed her in high fashion which she hated, but she was trying to please studio boss Jack L. Warner so that he would loan her out to RKO for the role of Mildred in Of Human Bondage (1934) - a part she desperately wanted to play and which would make her a star.
When the pianist tells Bette Davis, "Do a Helen Morgan," he is asking her to sit on the piano. Torch singer Helen Morgan was known for this.
The only film where Bette Davis and William Powell appeared together. This was Powell's last film at Warner Bros. before he moved to MGM.
Preview copies of the film listed Gene Markey and Katharine Scola as writers, but it was announced later they had nothing to do with the film. The Screen Writers' Guild was asked to take action against Warner Bros. for this breach of rules.
