I dunno, I think having re-animated corpses providing the voice-overs might be very interesting.
I, personally, want to see the "making of..." more than the movie itself though.... </me sits down with popcorn.. "ok, let's see how they made this thing..">
of course if they use zombies, that might hurt the dialog: "braaaaaaiiiiinnnnnnnzzzzzzzzz... Brrrrrraaaaaiinnnnzzzzz!" "no, no NO, the line is "welcome to Yliakum"! hehehe
