Here’s site I StumbledUpon that might be of interest to you: FreeDocumentaries.org. It is what it sounds like: a list of complete documentary movies that you can watch, drawn primarily from Google Video. I don’t imagine all of these will be available for too long; click “Watch this film” on the “Bowling for Columbine” page, for instance, and you’re greeted with a screener warning at the beginning of what is obviously and illegitimately posted copy of the movie.
