Let the film open. The media will mention it (amazing how much free press he gets), by week three it will be gone.
Ignore him. Don't be controlled by him. Believe me, people will not choose his film over the other drek in the theatre.
As usual the conservatives are carping about "enemies" and anti-americanism. It's always the bad guys, the evil-doers, the people out to get you. Someone even brought the Clintons into this thing. I'm sure this is all part of a well-heeled liberal plot. Just because someone is trying to present a side of the story that connects oil, cronyism and Bush to the house of Saud, the right-wingers get all in a tizzy. Open your minds for once. Sadly enough, this isn't even the nut fringe of the Consevative movement.
