Who is the most horrific movie vampire?

I had a difficult time narrowing down who should appear on my most horrific vampire poll, and I decided to limit the list to movies to avoid confusion between the film and literary versions of characters. Sometimes, a vampire comes across as appalling in a book, but they're toned down for their film adaptation, and vice versa (see Håkan from Let the Right One In).

Because there's so much interest in the attractive side of vampires, there aren't a whole lot of scariest vampire lists out there. At the top, you'll pretty much find Count Orlak from Nosferatu and Marlow of 30 Days of Night, so I thought it would be fun to have those two duke it out. To throw in an underdog, I'm also including Mr. Marlow from Salem's Lot, a movie that creeped me out when I saw it at a slumber party as a teenager.

Feel free to add your own personal choice of the Most Horrific Movie Vampire in the comments section. Here are some glamor shots of the nominees:
