what is a producer?

Answer 1

A film producer creates the conditions for making movies. The producer initiates, coordinates, supervises and controls matters such as fundraising, hiring key personnel, and arranging for distributors. The producer is involved throughout all phases of the filmmaking process from development to completion of a project.
You have different types of producers
Executive producer: In major productions, usually a representative or CEO of the film studio, although the title may be given as an honorarium to a major investor. Often oversees the financial, administrative, and creative aspects of production, though not technical aspects. In smaller companies or independent projects, may be synonymous with creator/writer.
Producer: the "classic" definition of producer who typically has the greatest involvement and oversight among a film's various producers. In smaller companies or independent projects, may be the equivalent of the Executive Producer.
Co-producer: A producer who generally reports to the (Executive) Producer and is more involved in the day-to-day production. He or she is the provider of money to finance a project. In independent projects, the title connotes an involvement in the inception of the production.
Associate producer: Usually acts as a representative of the Producer, who may share financial, creative, or administrative responsibilities, delegated from that producer. Often, a title granted as a courtesy or to one who made a major financial or creative contribution to the production.
Line producer: Oversees a film's budget and day-to-day activities
