Here's a suggestion for you vampire-o-maniacs out there: Get ready for Twilight - opening next Friday (as if you didn't know) - by checking out the very fine, very frightening Let the Right One In.
Based on the novel by John Ajvide Lindqvist, this cold, cracking Swedish noir centers on a misfit boy, Oskar (Kare Hedebrant), befriended by a strange 12-year-old girl who recently moved in next door. However, as Eli (Lina Leandersson) explains it, she's been 12 for "a very long time." She also isn't bothered by the frigid Scandinavian winter - maybe because her body temperature is already running at zero.
