Job Roles - Director

http://topyaps.com/top-10-hollywood-movie-directors

Directors are responsible for creatively translating the film's written script into actual images and sounds on the screen. They are ultimately responsible for a film's artistic and commercial success or failure.

Directors may write the film's script or commission it to be written, or they may be hired after an early draft of the script is complete. They must then develop a vision for the finished film and work out how to achieve it.

During pre-production, Directors make crucial decisions, such as selecting the right cast, crew and locations for the film. They then direct rehearsals and the performances of the actors once the film is in production. 

They also manage the technical aspects of filming including the camera, sound, lighting, design and special effects departments. 

During post production, Directors work closely with Editors through the many technical processes of editing, to reach the final cut or version of the film. 

At all stages, Directors are responsible for motivating the team to produce the best possible results. Directors must also always be aware of the constraints of the film's budget and schedule and manage the expectations of the film's financiers.
