This is one of those films that I've often heard mentioned, but never knew anything about, other than it had Marlon Brando wearing a long camel coat, and some degree of nudity. This is true on both counts, though 'some' could be something of an understatement, as barely a scene goes by without flesh being exposed, love being made or pleasure being administered by a character to themselves.
Our leads are Paul (Brando) and Jeanne (Maria Schneider, at the time a somewhat inexperienced actress). After several near-meetings and glimpses on the street and in a bar, she goes to rent an apartment that he has already entered. Without knowing one another's names, or anything else, the two engage in a burst of passionate, impromptu sex, before embarking on a relationship centred around the apartment, despite troubles in their personal lives and an obvious age gap of at least twenty years.
