 Actress Valérie Lemercier played the role of Frénégonde de  Pouille/Béatrice de Montmirail in the original "Les visiteurs"  (another actress was cast in this role for the sequel). She has a  small uncredited cameo as the mother of a boy who is watching  television instead of doing his homework. When Godefroy and  Jacquouille, disguised as two "flics" walk past her house, she  convinces them that they must come scold her son and scare him so  that he will return to his homework. It is a brief scene, about  midway through the film.
