As we think about scary movies for Halloween, I wonder what the vampires in “Twilight” or “True Blood” would think of one of the earliest screen depictions of a vampire, “Nosferatu.”  If the story seems familiar, it is because they wanted to film “Dracula” without paying for the rights to the original story.  A great mystery grew up around the actor who played the title role, Max Schreck, inspiring the Willem Dafoe film, Shadow of the Vampire.
