You know when you see the preachers down South? And they grab a believer and they go, "Bwoom! I touch you with the hand of God!" And they believe so strongly, they're on the ground shaking and spitting. And fuck's sake, that's the power of belief. Now, I don't believe in Jesus, but I believe in my performance. And if you can understand that the power of belief is one of the great tools of our time and that a lot of acting comes from it, you can do anything.
