We'll politely ignore the "Villain" Kre-on minifig that didn't exactly use his likeness, and note that the headsculpts we reported on a while back are finally attaching to their appropriate toy bodies. These won't be cheap, but 400 of them will come with authentic actor autographs - register your interest in a preorder now if you're willing to spend in the neighborhood of $250 for that kind of Benediction. Khan you pass it up?
Watson, I think, will get the short end of the stick, because it's cheaper just to customize a Bilbo toy. But you might have to buy him purely out of Hobbit.
