Welcome to Frames North

We write about documentaries and independent films the way a good programmer talks about them in the lobby: what the film is actually doing, who made it and how, and why it might be worth your evening. Some pieces are reviews and essays, some are practical guides to festivals, funding and the craft, and a fair number come back to Canadian screens, where so much of the world’s documentary tradition was invented.
