30 Days of Night (2008)

When the sun sets on the tiny Alaskan hamlet for the last time in 30 days, the population find themselves on the menu for a plague ship full of vampires. The local sheriff (Josh Hartnett) and his estranged wife (Melissa George) must fight to save who they can, but at what cost? A brilliant elevator pitch powers this gory siege movie, adapted by director David Slade from the comic by Steve Nile and Ben Templesmith.
