I recently made my own cut which eliminates every on-camera shot of General Grevious. He is a McGuffin whose sole purpose is to isolate Skywalker to make him more vulnerable to Palpatine's manipulations. He is now only referred to and never seen.

I used the ADM Extended Edition as my base as I wanted the inclusion of the birth of the rebellion scenes. I also cut the silly Matrix style part of the lightsaber duel between Anakin and Obi-Wan. I'll probably make more trims after I've watched it a few times, GG just had to go.....loathe him more than Jar Jar Binks.
