Anyways, I've never seen that Obi-wan/Maul desert thing before but it could be photoshopped...just a thought.
Also, like most everyone else, I always thought the turn scene was completely awkward and messy. The book does it a little better but it makes so much sense as to why it was like that considering the big change it went through. That son of bitch GL should have had that scene in his "visionary, not making it up as he goes" from the very beginning of writing ROTS. It was important.....too important, to just change whenever. If he thought people were gonna be confused then he should have worked the persuasion by Palp better (again, like the book), giving Anakin a clear obvious reason to stand by Palpatine without fail. The movie makes it seem like he made a quick decision to suddenly be bad and then acted like the only choice he had left was to join Palp, then later makes it seem like it was something he had been sure about for longer than that. It should have been that he thought out his decision and was slowly persuaded (seduced as the OT would have it) and finally determined that the only way to keep Padme alive was to stay by Palps side even when they came to arrest him. The way the old version of this scene seemed to want to play out was exactly as I think it should hace been.
Then again, i guess if he was already mostly persuaded to have made the choice to stick by Palp at his arrest (which I think was very soon after Anakin had told Mace about Palp being the Sith) then the Jedi would maybe have had to find out he was the Sith some other way....adding maybe another story line that might have sucked. But hey, we will never ever ever ever ever ever.....know.
