Like the blood-sucking vampires dramatized by their idol, fans of Buffy the Vampire Slayer creator Joss Whedon are always hungry, letting no series , comic book or musical web-blog go unconsumed. Into their gaping maw, then, we throw this: a just-surfaced clip from the pilot presentation for Whedon's aborted , animated Buffy spinoff. The gang's all here (sans series star Sarah Michelle Gellar), and even though the project was terminated years ago, it's a nostalgic hoot. Plus, cartoon Giles? Strangely alluring.
