Justin Timberlake and Anna Kendrick introduce the third trailer for DreamWorks Animation and 20th Century Fox's animated musical comedy Trolls, which includes behind-the-scenes clips and new footage from the movie. We have long known that Trolls will feature both original songs and classic covers such as Simon & Garfunkel's "Sounds of Silence," with this new trailer premiering a cover of the Cyndi Lauper classic "True Colors." We even get some behind-the-scenes footage as both Justin Timberlake and Anna Kendrick offer new details on their characters, the cranky Branch and the upbeat Poppy.

This trailer features Anna Kendrick explaining that her character Poppy is the "happiest troll of all the trolls," while Justin Timberlake's Branch is the exact opposite. Justin Timberlake also reveals that after the Bergens capture the Trolls, it's the music that saves them all. We also get another look at Cloud Guy (Walt Dohrn), who gets frightened after one of Branch's displays of aggression.

DreamWorks has also debuted a new website at DreamWorks.com/Trollify where fans can create their custom-made troll figures. Fans can customize every aspect of these trolls, from the length and color of their hair, to the clothes they wear, accessories and more. When you're done, you can share your very own hair-raising new troll on your own Facebook or Twitter pages.

From the creators of Shrek comes DreamWorks Animation's Trolls, a smart, funny, and irreverent comedy about the search for happiness, and just how far some will go to get it. This hilarious film transports audiences to a colorful, wondrous world populated by the overly optimistic Trolls, with a constant dance in their step and a song on their lips, and the comically pessimistic Bergens, who are only happy when they have trolls in their stomachs. After the Bergens invade Troll Village, Poppy (Anna Kendrick), the happiest Troll ever born, and the overly-cautious curmudgeonly Branch (Timberlake) set off on a journey to rescue her friends. Together, this mismatched duo embark on a rescue mission full of adventure and mishaps - trying to tolerate each other long enough to get the job done.

Utilizing music to further the film's narrative, the Trolls soundtrack is produced by Justin Timberlake and features five original songs including songs by Justin Timberlake and Gwen Stefani in addition to a number of classic hits from the 60's - 80's. The supporting voice cast also includes Christopher Mintz-Plasse, Russell Brand, Zooey Deschanel, Jeffrey Tambor, Christine Baranski, James Corden, Kunal Nayyar, Ron Funches, Icona Pop, Quvenzhané Wallis, with John Cleese and Gwen Stefani.
