Leonardo DiCaprio will no longer be lending his voice to DreamWorks Animation’s Rise of the Guardians, Variety is 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.
