Life after the undead


With the Fox series "Dollhouse" set to air in January, a continuation of his cult hit "Buffy the Vampire Slayer" running in its eighth season in comic book form and a new Web-only musical, "Dr. Horrible's Sing-Along Blog," released online this month, Joss Whedon has his hand in just about every medium. The multihyphenate also is producing MGM's "Cabin in the Woods." Whedon sat down in between panels at Comic-Con with The Hollywood Reporter to discuss new business models, comics and what comes next.
