Executive Producer
1. An executive producer of a motion picture is usually a person representing a financial investor in a film project, such as a film studio or a distributor, but who is not directly involved in the day to day production. It can also be someone with other special interests in the project, such as the author of the book that the film is based on, or one of the film’s key actors who has been instrumental in persuading the studio to do the film. In such cases, the executive producer credit is mainly honorary.
