Vampires were sexy way before Gary Oldman, Twilight, and True Blood. My apologies to the non-sexies: Bela Lugosi, Christopher Lee, Blacula, the cast of Salem's Lot (the creepiest vampire movie ever made - especially when you are 8), Brad Pitt, Tom Cruise, and most specifically Nosferatu.
If you haven't seen it, record it (it's on AMC on Saturday at 2:45 AM): Frank Langella. Dracula. 1979. Awesome music. And guess what - he didn't wear pretend fangs. Apparently Frank has the real thing, baby. Check out his crazy flicking eyes.
