You haven't heard? According to the Internet, he's supposed to be voicing a young, dark-haired cabin boy named James in the upcoming Disney Fairies movie, The Pirate Fairy. But, as the character has yet to make a visual or aural appearance in the trailers, I'm going to just call it an Internet rumor until there's some sort of proof (preferably a video clip from the movie itself).
Yeah, I know. But it makes me feel better if I pretend this is just another one of his big pranks, and the DVD comes with a small video of Tom saying "You've been LOI'D!" while some totally random voice actor plays James.
