Worst case scenario...

I ran across this thread somewhere in my wanderings, but cannot remember where, so I thought that I would propose it again, just for laughs.
Suppose that you wanted to film LotR and make it absolutely as bad as you could? I mean SO bad that it couldn't have been accidental. For parameters, add any actor from any time and even from other movies if it works. Also any strange or bizarre plot changes or dialogue rewrites, etc. I'm sure you know what I mean.
Here is my first contribution:
From the movie "Caveman", the misfit tribe as the Woses, with Atouk(Ringo) as Ghan-buri-Ghan.

Richard Lewis, or even worse, Norm MacDonald as The Mouth of Sauron
