The National Film Board of Canada has produced a documentary called Capturing Reality: The Art of the Documentary, and the website is incredible, featuring over 160 interview clips. Here’s their description of the doc:

Capturing Reality: The Art of Documentary is a film about contemporary documentary cinema and features some rock stars of the genre, including Albert Maysles, Errol Morris, Alanis Obomsawin, Michel Brault, Nick Broomfield, Kim Longinotto and Werner Herzog. Thirty-three filmmakers from 14 countries share their passion for documentary and talk about the artistic and ethical choices they make in their craft. Capturing Reality premiered at the International Documentary Festival Amsterdam and has been making the rounds on the festival circuit.

In addition to the 97-minute documentary film, there are over four hours of interview clips included in the DVD package.
