Guillermo del Toro: A Masterclass on Sound and Film

One of the functions of the director is to make sure that there are no departments that are independent in the visual realization of the film. Meaning... you create a series of parameters that are narrative, and that can be broken [down] into color, light, shape, form. That those disciplines are understood by all those departments. When you say, 'what great cinematography,' you're saying, 'what great production design.' When you say, 'what great production design,' you're saying, 'what great wardrobe.' And when you're saying, 'what a great image,' you're saying, 'what great set decorating.' And that's when the director does the job of the director — which is to make sure that these efforts are symphonic, to story and to character. So one of the mandates I give is: We're not creating eye candy, we're creating eye protein. And it should be nutritious. It should tell you something about the character. It should immerse you in a motif.
