I think of a film as an entity comprised of the egregore of the team working on it, the spirits of the filming locations, the story itself and what inspired it. Since its seed an idea has life of its own and its own intelligence. As a magician and film director I cooperate with this intelligence and help it to become what it wants to be. I do not limit it, I do not bind it. I let it grow. I listen to its voice. I let it surprise me.
Film can be a sigil or an evocation. The process of making it can be a magickal operation. If you treat it as such, the spirits will assist you and the universe will bring synchronicities your way.
