Many Directors participate in script rewrites ahead of production either on their own or with the Screenwriter(s). They also collaborate with department figures such as the Storyboard Artist, Cinematographer, Production Designer, and Head Costume Designer to establish the look of the film. Because they are responsible for getting great performances out of their Actors, a Director will also typically work with the Casting Director and their Associates during the casting phase of pre-production and give input as to who is chosen for a given role.
