Released in Germany on March 4th 1922, this unofficial Dracula adaptation gave cinema and media in general some of its most lasting horror imagery, vampire tropes (ie sunlight kills bloodsuckers), and timelessly creepy turn of Max Schreck as the verminous Count Orlok
In the 100 years since, the striking German expressionist visuals and unnerving Count of Murnau's classic has haunted horror cinema, its influence found in various vampires movies and shows since, from the terrifying Barlow of Tobe Hooper's Salem's Lot to the creeping shadow of Coppola's Dracula and more
Beyond the homages of shadowy figures and spidery fingers, Klaus Kinski and Willem Dafoe have embodied the Count themselves for radically different interpretations in the haunting Nosferatu the Vampyre (1979) and meta Shadow of the Vampire (2000) respectively
Nosferatu is in the public domain in the US, so for intrepid viewers or classic film fans, it shouldn't be hard to find. But Kino Lorber's edition is arguably the best way to watch, HD mastered from the 35mm restoration with an orchestral performance of the original 1922 score. That version can be found streaming on Shudder, Kanopy, Arrow, and elsewhere
