Some thoughts. Can you add a couple more annoying theater sounds? The rustle of candy wrappers, someone sucking the last microscopic drop out of a soda, or munching popcorn loudly? Candy wrappers were driving me nuts two weeks ago. ;)
It might be funny if Palpatine said "clone intelligence clones" instead of "intelligence units".
If you can extract "rise" from the ROTS teaser trailer, Palpy could say that to his lackeys to make them leave.
