The mind controls so much of the body. We are much more than flesh and blood we are complex systems. Patients do better when they have faith that they're going to do better. That's why I always tell my patients and their families not to neglect their prayers. There's nobody I don't say that to.
When I'm shooting a movie I'm always in an invisible theater seat. I respect the fact that people have worked hard all week and want to go to the movies on the weekend and be entertained.
