The film doesn't have a great script. All rely on the personal charm of Jean-Paul Belmondo, great and funny, as usual. A very young Sophie Marceau is also very charming and efficient. A not so young Marie Laforêt does what she can. Rosy Varte the same, even better, in a smaller role than Laforêt. Gérard Hernandez, small role too, the waiter from the Indian restaurant, is funny too. The music by Philippe Sarde is not great. Without Belmondo, with any other actor as the character Stephane Margelle, the film will be boring without shudder, without a charm. Jean-Paul fills the screen, he is the salt and the pepper.
