There is an impression that much of Hollywood opposes George Bush’s war on Iraq. But it’s more divided than that. “Producers, directors, writers and executives report heated disputes on sets, a sudden uptick in the use of the term ‘blacklist,’ an industrywide sense of confusion and a huge number of people changing their minds daily. There are not many conservative voices in Hollywood, certainly among the stars. But if you’re backstage, you hear a lot of sound people, makeup people and grips who are mostly supportive of President Bush. Even if they’re making $100,000 a week, actors like to think of themselves as rebels.”
