It’s all glitter and happiness in Troll Town until Queen Poppy and Branch make a surprising discovery—there are other Troll worlds beyond their own, each defined by a different genre of music. When a mysterious threat puts all the Trolls across the land in danger, Poppy, Branch, and their band of friends must embark on an epic quest through unfamiliar terrain to do the impossible: create harmony among the diverse Trolls to unite them against certain doom.

TROLLS WORLD TOUR boasts an all-star cast that includes returning cast members Anna Kendrick (Poppy), Justin Timberlake (Branch), James Corden (Biggie), Caroline Hjelt (Chenille), Aino Jawo (Satin), Ron Funches (Cooper) and Kunal Nayyar (Guy Diamond), who are joined by Sam Rockwell, Chance the Rapper, Anthony Ramos, Karan Soni, Flula Borg and Jamie Dornan, who will voice new characters for this all-new installment in the Trolls franchise.

With TROLLS’ Walt Dohrn back to direct and Gina Shay once again producing, TROLLS WORLD TOUR will be co-directed by David P. Smith. The film expands the series’ music genres, representing a variety of songs from pop, country and hip-hop, to hard rock, funk, K-pop and EDM—as well as everything in between.
