Glenn Erickson, the critic who calls himself DVD Savant, has spoken out against Lucas' revisionist history, so perhaps give him a shout-out. One could try Mark Kermode, though he's always hated SW. Maybe he could plug he petition on national radio in the UK. Shoot for any other critic you can; try maybe Alain Silver. He's friends with Christopher Coppola, which is a long shot, but hey, what the hell, Christopher's website might have contact info too. See if other critics have ways of contacting them on their websites; Kim Newman, Alan Jones, etc. Try letting any stars who Twitter or Facebook know. Make so much noise that it can be heard in places with limited media access. It doesn't much mutter, but anyway, try ANYTHING and everything with EVERYONE as soon as possible and get as many people as possible involved.
