Mike Mignola and Guillermo Del Toro team up once again to bring everyone's favorite wise-cracking, crime fighting demon to the screen in an animated adventure that finds Hellboy, Liz Sherman, and Abe Sapien pitted against a powerful horde of supernatural baddies. When a sprawling mansion becomes overrun with ghosts and werewolves, Hellboy is forced to put in some serious overtime to ensure that the situation doesn't get out of hand. Add into the mix a villainous vampires and a malevolent goddess, and you've got a recipe for Hellboy's most thrilling assignment to date. Ron Perlman, Selma Blair, Doug Jones, and John Hurt all return to voice the same characters they portrayed in Del Toro's rousing live action film.
