Personality is essential. It is in every work of art. When someone walks on stage for a performance and has charisma, everyone is convinced that he has personality. I find that charisma is merely a form of showmanship. Movie stars usually have it. A politician has to have it.
Nature generally struggles against this treatment for a while, until her powers seem in a great measure exhausted, when she quietly yields to the power of the art.
Works of art, in my opinion, are the only objects in the material universe to possess internal order, and that is why, though I don't believe that only art matters, I do believe in Art for Art's sake.
Which implies that the real issue in art is the audience's response. Now I claim that when I make things, I don't care about the audience's response, I'm making them for myself. But I'm making them for myself as audience, because I want to wake myself up.
Anybody can direct a picture once they know the fundamentals. Directing is not a mystery, it's not an art. The main thing about directing is: photograph the people's eyes.
