Vampire and comic book fans, your worlds are about to collide in gloriously gory fashion. Buffy the Vampire Slayer mastermind Joss Whedon is writing a one-shot comic book based on Buffy's BFF/friendly witch, Willow, for Dark Horse Comics, according to icv2.com. Alyson Hannigan, right, played the role on TV during Buffy's run from 1997 to 2003, but nobody knows yet if Whedon will base the comic character entirely on the actress. (Oh please, Joss, bring back Spike, too. He's the antithesis of all these lame, soft-hearted - so to speak - vampires we're stuck with today!) Look for the 40-page Buffy the Vampire Slayer: Willow to hit store shelves Dec. 23 - a perfect gift for your fave vampire lover (along with some wax fangs, of course).
