Trolls stars Anna Kendrick, James Corden, Gwen Stefani, and Russell Brand with original music by Justin Timberlake. The trailer provides no clarity as to what the film is actually about, but perhaps the description can illuminate:
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 comedicly pessimistic Bergens, who are only happy when they have trolls in their stomach.
It's no The Road to El Dorado.
