I was very interested in the Ginsburg article which talked about aboriginal filmmakers.
The National Film Board has a page discussing the history of aboriginal filmmakers and the NFB. This page also features a selection films at the bottom of the page.

This is a study that was completed about Canadian and international aboriginal filmmakers. It provides a bit of background to Canada’s aboriginal history, a summary of recent accomplishments in the field, and the current state of the industry.

I also looked up the production company begun by Rachel Perkins that was mentioned in the Ginsburg article.
