Yes, Sean Astin and Jon Voight were wearing flag pins and Chad Lowe was wearing a yellow ribbon(support troops). Most of the other actors who I know are "pro-war/Bush" did not have pins on and did not say anything at the podium.
They know this is not the time or place for politics.
Does anyone know who *specifically* in the audience booed?
I'm love to hear if any actors said anything about Moore after the show.
