Directors’ main duties include casting, script editing, shot composition, shot selection and editing. While the practical aspects of filmmaking, such as finance and marketing, are left to the producer, Directors must also always be aware of the constraints of the film’s budget and schedule. In some cases, Directors assume multiple roles such as director/producer or director/writer. Being a Director requires great creative vision, dedication and commitment. Directors are ultimately responsible for a film’s artistic and commercial success or failure.
