Names such as Wes Craven, John Carpenter, and Sam Raimi are all names that make people think of horror films.A Nightmare on Elm Street,Halloween, andEvil Deadare all long-running franchises that have made indelible marks on the horror genre.

However, it isn’t always established horror names that create an impact. Some of the genre’s most memorable films have been made bydirectors who aren’t knownfor horror, and who maybe never make another film in the horror genre. The following films are fantastic examples.

Nosferatu The Vampyre – Werner Herzog

Werner Herzog is known for his slow, often grim documentary works alongside his works of drama and fiction. He is also known for getting shot in the abdomen by an airsoft rifle during an interview and simply continuing on with the interview. Despite all of this, one of Herzog’s most famous films is the remake/re-imagining of the 1922version ofNosferatu. Herzog’sNosferatu the Vampyrestarred Klaus Kinski as the titular bloodsucker and Isabelle Adjani as Lucy Harker.

The film was praised for its aesthetic and for making the headlining vampire sympathetic and somewhat forlorn. With beautiful composition and a haunting melancholy throughout,Nosferatu the Vampyreis still acknowledged today as one of the great vampire films telling the story of Dracula.

An American Werewolf in London – John Landis

Frequently touted as thequintessential werewolf film,An American Werewolf in Londonhas left an indelible mark on horror cinema. Considering John Landis isn’t known for making horror films, it’s quite an achievement. The film sees American tourists David Kessler (David Naughton) and Jack Goodman (Griffin Dunne) trekking across the Yorkshire moors in England when they are attacked by an unseen creature. Jack is killed and David is injured, but little does David know he has received much more than an injury from the attack.

After waking up in London, it becomes clear that David is now a werewolf. Over the course of several days, David transforms at night and rampages through London, indiscriminately tearing people to shreds. The film is famous for its makeup effects and the grisly transformation sequence that turns David into a murderous beast.
