Film producers fill a variety of roles depending upon the type of producer. Either employed by a production company or independent, producers plan and coordinate various aspects of film production, such as selecting script, coordinating writing, directing and editing, and arranging financing. The average Hollywood film made in 2013 had just over 10 producer credits (3.2 producers, 4.4 executive producers, 1.2 co-producers, 0.8 associate producers and 0.5 other types of producer). During the "discovery stage", the producer has to find and acknowledge promising material. Then, unless the film is supposed to be based on an original script, the producer has to find an appropriate screenwriter.
