Answer 1

The director is the person who sets the tone of the movie and interprets the script as he sees it. He (or she) typically sees the story as a whole and gives it his own stamp. He instructs the actors on how to say their lines, their facial expressions and tone. Virtually anything that happens on a movie set is subject to the approval of the director. The final product is the direct result of decisions made by the director.
