)Here's a thought I've had for a while, though it may take a lot of work: Would it be possible to remove the three Jedi red-shirts from the frame all-together? Just paint 'em out and make the scene Mace "Jedi Badass" Windu one on one with Palpatine. It would certainly make Mace look arrogant going it alone to take down Sidious, but in the end foolish. It also puts a nice stamp on the Jedi's overall fall.
BTW, what's the eta on "Star Wars"?
