An Assistant Director (AD) is a person who helps the director in the making of a movie or television show. The duties of an AD include setting the shooting schedule, tracking daily progress against the filming production schedule, arranging logistics, preparing daily call sheets, checking the arrival of cast and crew, maintaining order on the set, rehearsing cast, and directing extras.

 A Director is a person who directs the making of a film. A film director visualizes the script, controlling a film's artistic and dramatic aspects, while guiding the technical crew and actors in the fulfillment of their vision. However, film directors do not in all countries have absolute artistic control. The director can also be selected by the producer. The producer can in this case have veto power over everything from the script itself to the final cut of the film, often in anywhere from slight to extreme opposition to the director's vision.

A Cinematographer is one photographing with a motion picture camera (the art and science of which is known as cinematography). The title is generally equivalent to director of photography (DP or DoP), used to designate a chief over the camera and lighting crews working on a film, responsible for achieving artistic and technical decisions related to the image.
