The Vampires Assistant, based on the popular series of books by Darren Shan, is a fantasy-adventure about a teenager who unknowingly breaks a 200-year-old truce between two warring factions of vampires. Pulled into a fantastic life of misunderstood sideshow freaks and grotesque creatures of the night, one teen will vanish from the safety of a boring existence and fulfill his destiny in a place drawn from nightmares. 　　16-year-old Darren (Chris Massoglia) was like most kids in his suburban neighborhood. He hung out with his best friend, got decent grades and usually stayed out of trouble. But when he and his buddy stumble upon a traveling freak show, things begin to change inside Darren. Thats the exact moment when a vampire named Larten Crepsley (John C. Reilly) turns him into something, well, bloodthirsty. 　　Newly undead, he joins the Cirque Du Freak, a touring sideshow filled with monstrous creatures from a snakeboy and a wolfman to a bearded lady (Salma Hayek) and a gigantic barker (Ken Watanabe). As Darren flexes his newfound powers in this dark world, he becomes a treasured pawn between the vampires and their deadlier counterparts. And while trying to survive, one boy will struggle to keep their brewing war from devouring whats left of his humanity. The darkly adventurous but fun score is by Stephen Trask.
