TrollsMusic can make you smile, laugh, and get up and dance. And in "Trolls," it's what can save happiness.

The second trailer for DreamWorks Animation's new movie features all of the colorful, hair-tufted characters, quippy dialogue, and zany background imagery as the first, but focuses more on the emotional journey. Stars Anna Kendrick and Justin Timberlake walk us through the trailer, explaining how their characters — the bright-eyed, bushy-haired Poppy and the curmudgeonly Branch — must team up to save their kind from the evil Bergens.
The actors talk about how important music is to the movie. "I think music adds so much to animation. I just think they belong together," Kendrick says. Both sing in the film, and Timberlake served as its executive music producer. "Trolls" features also features songs by their co-stars Gwen Stefani, Zooey Deschanel, and James Corden.

"Trolls" opens in theaters November 4.
