- The movie underwent several changes in cast and crew. Aurania Rouverol (of the Andy Hardy series) was signed to adapt the comic strip, with Gloria Blondell to star and Sam Marx to produce. Then Stuart Erwin and Una Merkel were to star in the film. Finally, Shirley Deane was cast as Blondie, but was replaced by Penny Singleton (who bleached her hair blonde for the role) when she became ill.
