Pretty much anything of
Geoff Lawton's is amazing to me, even if it has nothing to do with the region I live in.
Seeds of
Permaculture is a good documentary
https://www.youtube.com/watch?v=2cr10nOm0xU . As is
Permaculture: a quiet revolution

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.
