Not one that has been called a conservative. Hell I read today that Bruce Willis is now on the "911 was an inside job" bandwagon. This really sucks.
... Except for one thing: Mel Gibson has a grain silo full of golden Spanish doubloons. Easily over 100 million bucks, and that's just my guess. It's probably lots more.
Kinda hard to hurt a famed director with that kind of loot. If he makes money, they will deal with him.
