Trolls Band Together, the third installment in the animated franchise, has an all-star cast that includes several popular musicians. DreamWork's adventure comedy series has always been music-centric. Still, the third movie takes the musical element to the next level by including a much-awaited boy band reunion and some of the biggest names currently in pop. The film also includes actors like Anna Kendrick, Daveed Diggs, and Andrew Rannells who, while known primarily for acting, are talented singers on both the stage and screen. They contribute their voices to Trolls Band Together's songs, but so too do many professional musicians.
