thank you for mentioning #6. Not enough people realize that the film itself isn't the end product.. the commitment to view a film creates an EVENT which becomes a node of a bunch of related meta-data about the attendees. All this data spread out across the world in different regions, creates services/jobs/products by people who can correlate the information into forecasting trends.

For example...
Within a month, you see new memes born online and evolution in women's fashion.
Within a year, you start seeing new inventions, and engineering-design trends.
Within 5 years, new social policies and flavors of sub-cultures.

Entertainment is a powerful thing. =)

Interesting read.. so what happens to the Producers with functional creative roles and also funding the movie? Is that a third classification?
