What you want is a comfortable environment that you feel you can invent in. Because film is such a lumbering, technical, huge, great Neanderthal thing, it's hard to create that little space of peace, and calm, and creativity, and ease. That's what you want the director to create for you, so that when you walk on the set, you forget all of that, and the fact that it's costing gazillions of dollars a second.
Chemistry comes about through the transformation of earth, air, fire and water. All chemistry is just movement within those things, and so we experience the joys and the sorrows of hot and cold, and dry and moist, because of these chemical transformations. In a similar way, we create and experience a world of time, space, motion and energy, through our intuitions, our thoughts, our sensing and our feeling.
