This documentary includes footage from almost every vantage point (and impressively edited together) during the Oka crisis in 1990 which I had never heard of before (http://en.wikipedia.org/wiki/Oka_Crisis).

Two more documentaries on the standoff:

• Acts of Defiance (http://www.nfb.ca/film/acts_of_defiance/)
• Rocks at Whiskey Trench (https://www.nfb.ca/playlists/alanis-obomsawin-retrospective/viewing/rocks_at_whiskey_trench)
