A producer basically supervises the entire filmmaking process. From the acquisition of ideas and scripts, to hiring directors and actors, to production and post-production parts of the filmmaking process, the producer oversees all. That is a very broad job description but one that is essential. The producer hires people to write scripts or they purchase scripts that they think would translate well into great movies. They shop around for the right studio to invest in the movie and from there, the producer gets the ball rolling by hiring creative talents and technical crew.
During the production process of the movie, it falls upon the producer to troubleshoot any problem that may arise, whether it involves the actors, the directors, the crew, the schedule or the budget. Most of the time, the producer keeps their distance in the actual production of the movie, letting the film director, the actors and the crew do their jobs the best way they know how. They may offer suggestions and recommendations, but most of the time they simply observe, monitor and review how the movie is going. After production, the producer can be involved in selecting the scenes to be included in the final cut of the movie. As soon as the final cut is determined, the producer works on distribution and advertising.
