Leonardo DiCaprio will no longer be lending his voice to DreamWorks Animation’s Rise of the Guardians, Variety┬áis reporting. The actor had previously been announced to voice the lead character of Jack Forst, a role which Star Trek leading man Chris Pine will now be taking over. The story finds Frost as a member of an elite team of fantastical characters, including Santa Claus (Alec Baldwin), the Easter Bunny (Hugh Jackman) and the Tooth Fairy (Isla Fisher). The heroes will face off against a villain named Pitch, voiced by Jude Law. Rise of the Guardians is set to come to theaters in time for the Thanksgiving weekend of 2012.
