One of the things Rohmer does which I have not seen with any other director is to take a location, seemingly dull, far from beautiful and somehow he renders it of utmost important to his story. In 'La femme d'aviateur' it's the interiors of Paris apartments and a moderate park in Paris called Le Parc de Buttes Chaumont. In 'Pauline a la plage' and 'Le Rayon Vert' there is an emphasis on the changes in people when you take them out of their daily routine and normal environment, specifically when they are on vacation, a very important part of French life.
In this film 'Les nuits de la pleine lune' (Full Moon in Paris) and L'ami de mon amie', he films relatively new suburbs of Paris with new ideas on architecture, new ideas on living and with young successful people. Most directors would never bother to even visit these grotesque modern suburbs, let alone film a film there. However it works with this film and L'ami de mon amie'. Why I don't know, but we know that it is a crucial element to the emotional journey of the main character in this film - her displacement between Paris and the suburbs. She prefers the chaos of Paris to the straight lines and cubism of her suburban apartment.
I thought Pascale Ogier was fantastic as the lead in this film. I think Rohmer has a fantastic knack for choosing lead woman, with only one exception in my mind to this rule. They are usually petite, fragile, mystically beautiful.....What I thought of when watching Pascale Ogier as Louise was a cat. Her slinky movements, her lazy eyes, her calmness, her desire for space - not your average women. I read just one year after making the film she died of a heart attack at the age of 26.
All in all an average or above average Rohmer film (which it not a bad thing). It sweeps over you with it's subtle charms and before you know it you will be under the film's spell.
