I've always tried to have a rule that you shouldn't make fun of innocent people who can't defend themselves. I find that a little unseemly and distasteful. But nothing's really sacred to me.
Bob OdenkirkNot to knock the people who've given me the opportunity; I appreciate all the opportunities I've gotten, but one of the things I think I really learned from the features I got to direct is that your job as a director is everything about the movie. It's to pick a story that's really worth making, and make sure that the basic components are there. You're not just a part of the team. You're really in charge, and the responsibility falls on you if all the components aren't there for a worthwhile film.
