It's Not My Business(1962)

A small-scale cabaret troupe is touring the provinces. One afternoon while canoeing, Monique Darzel, one of the troupe's singers, spots an angler whose resemblance to Fernand Raynaud strikes her. She discusses this with Jean Duroc, the troupe's director, who laments the meagre revenues his show is raking in. He then had the idea of meeting this fisherman to convince him to imitate Fernand Raynaud in his shows. It turns out that the Fernand Raynaud impersonator is in fact Fernand Raynaud himself, who has come for a week's incognito vacation in the provinces. Raynaud is finally persuaded to play the novice comedian, in order to further develop the script for his next film, Les cabotins à travers les âges.
