A director must speak the language of an actor, editor, camera operator, sound engineer and so on so as to successfully accomplish the making of the film. Therefore, directors must have technical, creative, interpersonal and leadership skills so as to manage all the responsibilities of his job and that are the financial and the creative success of a film.
Of course, if you're making an animated film and you're a one man show as many of us are, you can dispense with the interpersonal and leadership skills, though it means you do have to be extremely self-motivated and disciplined. But as soon as other people are directly involved in the project then those skills are required as well.
