Les vampires

An intrepid reporter and his loyal friend battle a bizarre secret society of criminals known as The Vampires.

Director Louis Feuillade is something of a legend, having directed an astonishing 630 films in the silent era (and perhaps more). He is best known for "Fantomas", the serial he made prior to "Vampires", and while the former may be marginally superior, they are both exquisite in their own way, and a great example of early thrillers.

Indeed, it is quite impressive that a film is seven hours long and still exists one hundred years later. Given how many silent films have since been lost forever, it is incredible that Feuillade's work seems to be intact and in great shape.
