This link http://anthfilm.anth.ubc.ca/index.html takes you to the website of the ethnographic film unit at UBC. Situated in the department of Anthropology, it undertakes research and film production from the perspectives of anthropologists, filmmakers, students, and community members (I assume at least some of whom are aboriginal, based on the topics of their films).
Many of their films and related curriculum packages have First Nations themes and topics. These resources are available for sale on their site.
