Nosferatu- Old vampire movie. This if one of the first creepy movies ever made. Something about the silence coupled with the dreamlike picture quality of old film makes this movie super weird and awesome. Supposedly the actor who played rat teeth-long fingers was even creepier in real life. This just seems to add to the overall psychological disturbance of the film. Even today I can't not be creeped out by it.
Before Twilight film makers knew they needed to keep changing vampires. Instead of being a horror movie "The Little Vampire" was aimed at children. Rather than giving kids nightmares film makers wanted kids to think vampires were cool.
