It’s here: The 3rd edition of Introduction to Documentary, first published in 2001. Lots of updates and photos from new and older films, but the biggest changes is a brand new chapter, “I Want to Make a Documentary: How Do I Get Started?” It covers key aspects of preproduction from the pov of what funders tend to look for and what a filmmaker needs to convey.
The book size is a bit larger and that makes for a really nice lay out of tables and photos.
