More specifically, Les Vampires (1915), a 10-part serial by Louis Feuillade.
We’re following this extension of the Saturday Silent all week until Halloween, when the most famous vampire of them all will show up. Here are parts 3 and 4 and parts 5 and 6, as well as parts 7 and 8.
Ladies and gentleman, here is the conclusion of Les Vampires!
Thanks again to P. Emerson Williams for putting this entire 8-hour series online.
