Oh believe me, I know. It's why Mel Gibson had pretty much no backing for "The Passion" (which only turned out to be one of the biggest blockbusters in history), and why a patriotic 9/11 movie is a fantasy that will never happen.
Well Passion was not a political film. It had nothing to do with U.S. It didn't get backing because the Studio execs like playing it safe. There was no precedent for a movie like that doing any business. You can be sure there will be backing for Mel's next project. Just like they hired his promoter to publicize the upcoming Narnia film.
"Mel Gibson had pretty much no backing"
Speaking of which, I haven't been hearing anything about his next project.
