"It doesn't do to say that heresy produces the development of doctrine, because that annoys the theologians. But it is true to say that as a matter of history the development of doctrine has been largely a reaction on the Church's part to the attacks of heresy."

There's nothing worse than the frustration of having somebody who you feel doesn't get what you're doing, trying to turn it into something else. It's a very, very annoying and sort of frustrating thing and I just never wanted to go through it. I was very fortunate as I came up through the film business that I was able to insulate myself from that.
