Producer, Director and Distributor rolls

Roll of the Producer;
Film producers prepare and then supervise the making of a film before presenting the product to a financing entity or a film distributor. They might be employed by a film studio or be independent, yet either way they helm the creative people as well as the accounting personnel. Producers can often not personally supervise all parts of their production. The reasons are many. For example some producers run a company which also deals with film distribution.

Director;
A film director is a person who directs the making of a film. Generally, a film director controls a film's artistic and dramatic aspects, and visualizes the script while guiding the technical crew and actors in the fulfilment of that vision. Film directors create an overall vision through which a film eventually gets made. Realizing this vision includes to oversee "the cinematography and the technical aspects" as well as directing the shooting timetable and meeting deadlines.

Distributor;
Often looked on as middlemen that add costs to material purchases, distributors are, in fact, a vital link in the composites industry, bringing tangible benefits to both material suppliers those manufacturing the materials and end-users. The distributor, who buys large material quantities from a supplier/manufacturer, then creates smaller material units and delivers those units to many customers, in a timely fashion. They are distinct from brokers, who neither take delivery or nor title to the material, and surplus buyers, who typically buy aged material or overage and resell it at a discount.
