Knowing PJ though...he's bound to put those heads flying...Do you actually know him, as in "Hey, Peter, how's things?" or know him as in, based on LOTR, I think Peter will do thus and such in TTT?
Always good to have inside info...
Just by seeing the things that he's done with FOTR and TTT. I don't know him personally, no. :-)
But I'll bet you anything he has those heads flying.
