Billy Crystal to Play Aging Vampire in Webisode

The Hollywood Reporter magazine reveals how the actor-comedian was roped in for a "Funny or Die" short.

Vampires are big in the youth market, we know -- but they're about to skew older. A lot older.

Billy Crystal has been cast by Will Ferrell to play an aging vampire in a brief webisode for Ferrell's comedic website Funny or Die.

Crystal needed a partner -- so he called old pal Renee Taylor, who told her friends, "Billy's going to bite my neck, but carefully -- we're senior vampires!"

Let's hope no teeth are broken during the making of the show.
