Exactly what does a Hollywood/TV Producer do?

I was watching the season premier of "Leverage," and I was amazed at how many "Co-Executive Producers" there were. So, of course, it aroused my curiosity as to exactly what all these producer titles were about. I did a little digging and came up with these definitions from a How Stuff Works web article entitled How Movie Producers Work.

Executive Producer -- Supervises one or more producers as they perform their duties for one or more films. The executive producer may represent the film studio and keep watch over the producer to make sure the movie is within budget and being made the way the studio wants. Or the title may be given as a symbolic gesture or to give a movie visibility. George Clooney, for example, was listed as executive producer for "Far from Heaven" (2002) to generate publicity, but didn't spend any time on the set, according to the film's producer Christine Vachon.

Associate Producer -- Handles certain aspects of production, as assigned by the producer. Usually the associate producer has worked through all three stages of the production, from preproduction to post-production. Sometimes the associate producer title is given as a courtesy title to a key backer of the film who does not have a major role in producing the film.

Assistant Producer -- Works on tasks assigned by the associate producer.

Co-Producer -- Shares producer responsibilities as a team or group with other producers. One producer may take on creative responsibilities while another handles business functions. Or one of the producers may be a major investor who is not directly involved in the movie production. Or a co-producer may have brought the script or the film's star to the production.

Supervising Producer -- Oversees one or more producers as they perform some or all of their duties. The supervising producer may take the place of an executive producer or work for the executive producer.

Coordinating Producer -- Coordinates the work of several producers to create a unified end result. Coordinating producers are valuable when a studio produces several related films, as with "Spiderman," or particularly when two related films are being produced at the same time, as with the two sequels to "The Pirates of the Caribbean."

Line Producer -- Handles the physical aspects of a movie's production and usually is not involved in decision-making regarding creative issues. This is the person who oversees the budget and day-to-day activities during filming. In addition to making sure the movie stays on budget and on target, the line producer handles any crises that may occur.

Almost as many producers as Carter has pills! And if you remember where that phrase came from, you've been on this planet quite a while...

The article runs several pages, and I recommend it as a good way to start to understand what producers do, how the great ones got started, etc. If you're a TV or movie buff, this is a worthwhile read. Besides, it might pique your interest enough for you to become the next great producer!
