In "We Won't Grow Old Together," Catherine(Marlene Jobert) and Jean(Jean Yanne) have been having an affair for six years. Despite his being married for eleven years to Francoise(Macha Meril) and Jean and Catherine's apparent inability to get along together, Jean decides he wants to move to the next level with his mistress by retrieving his grandmother's engagement ring.(If one were of a cynical outlook, then one could say that Jean's tragedy comes from treating his mistress like his wife and his wife like his mistress.) However, even though she has long wanted to get married by the age of 25, Catherine balks at this proposal which drives Jean further up the wall. In case you are wondering, frequent traveler Francoise has long known about this affair, as do Catherine's parents(Christine Fabrega & Jacques Galland). Only in France.
You can have your flashy alien invasions. I'll take a dreary domestic drama, any day, thank you very much. And with "We Won't Grow Old Together," we have the 1972 World Passive Agressive Champions. What stops the movie from fully succeeding is not the volume level, but the movie's structure, jumping from one episode of arguing and put-downs(rat thighs?) to another, possibly making the audience wonder if the couple hadn't already...before the movie eventually just comes to a halt. So, maybe a non-chronological structure would have been the way to go.
