Attention “Buffy the Vampire Slayer” fans: Creator Joss Whedon dropped some hints lately about a possible made-for-TV movie featuring one of Buffy’s favorite bloodsuckers, Spike, otherwise known as “William the Bloody.” In his interview with Australia’s “Moviehole” Web site, Whedon stated that “…(we) can only teasingly hint unfortunately until it’s got backing, and we’ve got a schedule and a contract.” But are viewers ready for another foray into the dark side with a Billy Idol look alike? Probably. Let the bloodbath begin.
