Anna Kendrick was unsure who the rude troll was:“Actually the first time that I heard his speaking voice in ‘Trolls’ I was like ‘who is that?’. I was like ‘he is so mean’, cause at first he is very mean to me.’‘

Timberlake also served as executive producer on the film’s soundtrack, mixing original compositions with mashups of classic songs.

‘Trolls’ is being released worldwide this Autumn.
