With just four days to go before the release of the very promising 30 Days of Night, Sony Pictures has posted one hell of a teaser clip on its website. If this doesn't get you pumped to see this very Romero-flavored vampire pic, nothing will.Based on the acclaimed graphic novel by Steve Niles--who also penned the 2004 Frankenstein re-imagining Wake the Dead--30 Days tells the tale of a small Alaskan town terrorized by the unruly undead each year when the sun disappears for an entire month. This one should do for vamps what the Dawn of the Dead remake did for zombies.
