Something I think worth mentioning is there isn't a lot of what I would call a proper documentaries about permaculture. While there are some yes, most of the permaculture stuff seems to be more talks and presentations, or youtube videos of what people are doing. Rather than full on documentaries. Likey due to permaculture being such a large inclusive umbrella of a lot of techniques. It is hard to do a documentary including everything, so a lot of videos dedicated to parts and pieces are out there.
In that light I really like Ben Falk's videos. And pretty much anything from Permaculture voices. I also really enjoyed Mike Oeler's 3 dvd set on underground/earth sheltered homes. And of course the RMH DVD set was amazing.

Abundant Land by Natasha Florentino is a great example of permaculture on Molokaʻi, Hawaiʻi: "A documentary film about a Hawaiian community’s efforts to repair the ecological trauma caused by industrial agriculture." -Kickstarter
