You work with every actor differently. It's like if you're a mother, if you have children, some children need more discipline. Other children you back off of a little bit and let them be. It's the same way with actors. Some actors need a lot of hand holding. Other actors like to be let be and you let them go. Some actors like to be nudged just a little bit. Some actors don't mind line readings.
Fanaticism is such a blind stuff that it can never give you any idea as to what is reality. Because whatever you believe into, you build up your own ideas and everything onto it and it's like a fake palace built on a fake idea. And then you go on fighting. If God is one, if His love is one, then how can people who believe in God fight?
