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.
For various reasons, producers cannot always personally supervise all of the production. As such, the main producer will appoint executive producers, line producers or unit production managers who represent the main producer's interests. Among other things, the producer has the last word on whether sounds or music have to be changed or scenes have to be cut and they are in charge of selling the film or arranging distribution rights. The producer's role can vary significantly from project to project and based on the circumstances and funding.
The musical film is a film genre in which songs sung by the characters are interwoven into the narrative, sometimes accompanied by dancing.
The songs usually advance the plot or develop the film's characters, though in some cases they serve merely as breaks in the storyline, often as elaborate "production numbers".
The musical film was a natural development of the stage musical after the emergence of sound film technology. Typically, the biggest difference between film and stage musicals is the use of lavish background scenery and locations that would be impractical in a theater. Musical films characteristically contain elements reminiscent of theater; performers often treat their song and dance numbers as if there is a live audience watching. In a sense, the viewer becomes the diegetic audience, as the performer looks directly into the camera and performs to it.
