One might be looking for Nosferatu (White Wolf) which refers to a clan of vampires.
Stoker's estate sued for copyright infringement and won. The court ordered all existing prints of Nosferatu to be destroyed, but a number of pirated copies of the film had already been distributed around the world. These prints were then copied over the years, resulting in Nosferatu gaining a reputation as one of the greatest movie depictions of the vampire legend.
In 1979, Werner Herzog directed a remake of Nosferatu. Filmed on a shoestring budget (as was common for German films during the 1970s), Herzog's Nosferatu was a critical success, considered by many to be a faithful homage to Murnau's original film.
In 2000, a Hollywood movie called Shadow of the Vampire told a fictional story of the making of the silent version of Nosferatu. Starring John Malkovich and Willem Dafoe, it was a fantasy-horror story of a film director (Murnau, played by Malkovich) who created an utterly realistic vampire movie by hiring a real vampire (played by Dafoe) to play the role of the vampire.
