This is what I think of a director as. I dont really think of the director as being a job in itself, but rather, he is everything, the cinematographer, editor, production designer, sound mixer, etc. along with having the job of having to direct the actors' performances. And particularly in low-budget films, this is true: the director IS actually everything. A few people above said that the director's main job is to work with the actors. I think that's maybe true for theater, but not so much for film. Film is a highly technical art. Some people also said the director is the person who makes all the artistic decision, not the technical ones. I agree with this by the fact that directors do make mostly artistic decisions, but that's not to say they dont make technical decision, nor to say that they shouldn't have any technical knowledge at all. In fact, I think it should be the director who has the most technical knowledge overall, so that he or she can better use it towards creating an interesting film. So I think it's wrong to say the director mainly works with actors, or he mainly controls the shots and takes of a film, because the director doesn't and shouldnt mainly work with anyone, he should work with everyone as necessary to get a good film.
