After Ernest Bourbon attends a stage magician's act, his possessions suddenly have magical powers: confetti emerges in abundance for his hat, ladies disappear underneath his umbrella, and so forth.
Did I even look at the correct movie? 'le physicien', according to the online translator, means no 'physician' or 'doctor' but 'physicist' and 'stage magician' in French is 'magicien de scène'. Is this some other adventure of Onesime? If so, it's not one listed in Bourbon's IMDb credits. Well, it wouldn't be the first time a movie was mislabeled, nor a credit was left off this august website.
All in all, it's an enjoyable short.
