Director:
A director is the person who directs the making of a film. The director most often has the highest authority on a film set. Generally, a director controls a film’s artistic and dramatic aspects and visualizes the screenplay (or script) while guiding the technical crew and actors in the fulfillment of that vision. The director has a key role in choosing the cast members, production design, and the creative aspects of filmmaking. Under European Union law, the director is viewed as the author of the film.
Producer:
A film producer creates the conditions for filmmaking. The producer initiates, coordinates, supervises, and controls matters such as fund raising, hiring key personnel, and arranging for distributors. The producer is involved throughout all phases of the film making process from development to completion of a project. There may be several producers on a film who may take a role in a number of areas, such as development, financing or production.
Executive producer:
An executive producer (EP) is a producer who was not involved in the technical aspects of the filmmaking process in the original definition, but has played a financial or creative role in ensuring that the project goes into production. Today, however, the title has become ambiguous, particularly in feature films. Since the 1980s, it has become increasingly common for the line producer to be given the title of executive producer, while the initiating producer takes the “produced by” credit. On other projects, the reverse happens, with the line producer taking the “produced by” credit. So the two credits have become effectively interchangeable, with no precise definition.
Location manager:
Oversees the locations department and its staff, typically reporting directly to the production manager or assistant director (or even director or executive producer). Location manager is responsible for final clearing (or guaranteeing permission to use) a location for filming and must often assist production and finance departments in maintaining budget management regarding actual location/permit fees as well as labor costs to production for the locations department at large.
Digital service:
Since the turn of the 21st century, several additional professionals are now routinely listed in the production credits on most major motion pictures.
Social publicist:
The publicist liaises between the film production and the media. They create press releases, in collaboration with the producers, and work with the unit still photographer.
Legal counsel:
Entertainment lawyers negotiate contracts, clear licensing rights for any intellectual property used in the film, obtain tax credits from local governments, and take care of immigration paperwork when cast or crew cross international borders to shoot on location.
System administrator:
A system administrator or sysadmin, is a person employed to maintain and operate a computer system or network. This role is increasingly important for digital monitors on set, digital intermediate editing and post production, digital effects, digital sound, and sometimes for full digital production.
