"Unless noted before, the script for this was started years ago - like in the 70's."
You believe the script for this movie is exactly the same as it was 30 years ago, and hasn't been altered over time?
My understanding was that Lucas had the overall story in mind, and fleshed each movie out as he made them.
Its just that liberals who have seen early screenings of the movie see "hate Bush" every waking moment. Then they reported it on DU and then Katie Couric reported it Today.
Lucas, BTW, is a one of the more conservative Hollywood moguls.
