"fat guy who directed the Lord of the Rings movies" is going to fake the Mars program.
I hope not. If you have seen all his movies you'd know that he has a love of killing off at least someone in a bizarre and grusome way in his movies.
Added to that is the problem that there is nowhere in NZ that resembles Mars, so he'd have to film it in the Ozzie outback, and they have claimed enough of our top people already without them claiming him.
And finally, have you seen PJ lately? He's lost a HUGE amount of wieght. He's quite literally only half the man he used to be.
