Remember when Julie Andrews in The Sound of Music says "Every time God closes a door, He opens a window?" Well, this is basically the same philosophy followed by a sage authority named Professor Azais. Though he is never seen in the film, Azais's influences dictates every move made by Le Baron Wurtz (Max Dearly), a private tutor. Though he suffers quite a few setbacks, Wurtz presses on, armed by the Azaiz philosophy that every time something goes wrong in one part of the world, it is balanced by something going right elsewhere. This "law of compensations" pays off in big laughs for the audience, and in a happy-ever-after for Wurtz. Azais was based on a play by Georges Berr and Rene Verneuil.
