From the creators of Shrek comes the most smart, funny, irreverent animated comedy of the year, DreamWorks' Trolls. This holiday season, enter a colorful, wondrous world populated by hilariously unforgettable characters and discover the story of the overly optimistic Trolls, with a constant song on their lips, and the comically pessimistic Bergens, who are only happy when they have trolls in their stomach. This trailer for 'Trolls' is in HD.
