Expand your post, Carlos. Nobody is a natural born filmer, those directors acquired their skills over a distinctive set of experiences that shaped their work.
I think that a Natural Born Filmer would be a filmmaker that his career show nothing but perfection. It is, certainly, a vague post, but just think of the work of Luis Buñuel. A career without a bad movie. Perfection. That is a Natural Born Filmer. I suppose.

Can we consider some directors as Natural Born Filmers? Example: Kurosawa, Kubrick, Fellini, etc.
