Amazing, one of the best movies seen in years. Finding it was a total surprise, since I had never heard of it. Yet it should keep company alongside Renoir's "La Regle du Jeu" (also 1939) or Carne's "Hotel du Nord" (1938).
The story features the sharp edges of Wilder's "Sunset Boulevard" (1950) sanded down by the spirit of Leo McCarey. One of the rare, non-grating performances by Michel Simon. Also standouts from Victor Francen and Louis Jouvet. Francen in the 1930's already plays a senior citizen, yet he will appear in films of the 1960's looking hardly any different. Louis Jouvet, after starring in "Hotel du Nord" is at his best here as St.-Clair, an egotistical, sinister cad whose shortcomings are revealed with realism leavened by sympathy in the Duvivier-Charles Spaak script. Few actors have portrayed evil with the depth and complexity of Jouvet in this movie.
To describe any of the plot points would only detract from the experience of watching this movie. Relating just about any incident would amount to a sort of "spoiler", since I think I appreciated this film so much because I knew so little about it. Viewing should precede reading where this movie is concerned.
It is enough to say that "La Fin du Jour" belongs on any list of great movies.
The subject matter of the lively arts appears frequently on screen. If you like "La Fin du Jour", I could recommend "Floating Weeds" (1958) or "For Fun" (1993), members of the same family in spite of being many years and many miles away from Duvivier's world.
