That face is one of the most versatile (not to mention the most beautiful) in the history of cinema. At the conclusion of the film's best scene-- as Dr. Schoen's fiancee catches him red handed in Lulu's dressing room-- her competitor slowly dismounts him with a momentary smirk full of hurt and disdain, yet somehow ballsy and triumphant.
Such precious and sophisticated details make "Pandora's Box" a masterpiece. The title itself is mentioned in an inevitable courtroom scene midway through the story, by a prosecutor who crudely accuses the girl of being the root of all evil. This is where the film's sociological implications make it stand out from many of its contempories. Louise does not portray a conniving temptress.
