They then work with producers and casting directors to select the actors and with the director of photography to develop the filming style, including notes about camera shots and script changes. Some directors rehearse actors ahead of shooting, though not all do. They ‘block’ the performance with the actors before filming begins, meaning they choreograph where actors are positioned, where they will move to over the course of a shot and how they will deliver their dialogue. At the same time, a director will also be instructing other members of the crew, especially lighting, wardrobe and make-up supervisors. Directors work to get the best performance out of the actors but also need to ensure that all technical aspects are in place to get a great scene filmed.
