In the original script written by Fleming Lynge and Paul Sarauw, the month of the bet was October, but, possibly because the film's release was set for March 1st, it was changed in the film to the month of March. The original script does not include the songs, which were written separately by Kai Normann Andersen, and there are a few small situations lasting mere seconds that have been changed, must mostly the film is a word for word adaptation of Lynge and Sarauw's script.
