One of the key parts of film production at Ranco Studio is the production management department. The production manager in filmmaking is the one who gets the budget to spend it in the most economical way. He knows the details of the work. He is responsible for overseeing the employment of actors, locating, purchasing or renting equipment and facilities, and even the transportation and food ordering sector, etc., so that he can use the least expensive and at the same time the best way to hire them. The production manager usually acts formally under the direct supervision of the executive producer.
