“Sold on DVDs and CDs, with names like “Film School in a Box” and “Make Your Own Damn Movie,” these programs, often conceived by people with no formal film training of their own, offer surprisingly detailed tutorials on a variety of film-related topics: blocking, editing, even fund-raising and distribution. Priced roughly from $50 to $500, they can instill confidence without the bother of hundreds of thousands of dollars of a formal education. Whether they can really teach how to make a good movie remains open to debate.”
