The first vampire movie, released all the way back in the early 1920s, was loosely based on Bram Stoker's Dracula, but took the eponymous vampiric Count and transformed him into the terrifying Count Orlok. Nosferatu unsettled audiences at the time, relying on images to belay terror, as movies were silent during this era. It was undoubtedly influential in other vampire movies, inspiring Barlow from Salem's Lot, and even Petyr from What We Do in the Shadows.
