The film is based so exactly on the courtship of Ruby Keeler and Al Jolson that Jolson, having read the script, knocked out Walter Winchell when they met accidentally at the Hollywood American Legion stadium on the night of July 21, 1933. Keeler, who was a dancer at Texas Guinan's nightclub, was dating gangster Larry Fay when she met Jolson. Fay visited Jolson after hearing of this just to tell him that he could marry her.
Allthough 'Modern Sources' (according to AFI notes) have credited Ann Sothern with an uncredited appearance in this film, she is not in it. One reviewer mistakes her for one of the two blondes at the beach (the other one is Lucille Ball), but the one in question is Edith Allen. Nor is Sothern included in any of the dance ensembles.
The Hollywood Filmograph reported that a role originally slated for Peggy Hopkins Joyce has been recast with Lilyan Tashman. The article does not state which role this would be; neither Joyce nor Tashman appear in the final film.
Final film of actress Texas Guinan.
