I see that the National Film Board of Canada is putting a number of its documentary, shorts, and experimental films online for free viewing. Many of them are full length with many others just having excerpts.
I remember as a grade 2 student many years ago watching a 1966 film entitled, “Paddle to the Sea.” For some reason, it was one that stuck in my mind. I don’t remember all the details, but there are definitely some scenes etched in my memory. The film is about a little hand-carved boat that a native boy makes and throws into Lake Superior. The film documents its progress through the waterways until it eventually reaches the ocean. One scene in particular that I remember was the boat going through some sludge. That really troubled me to think that some of our water was so polluted. Unfortunately, the film isn’t available in its entirety, but you can watch a short clip here.
For a hilarious short animation, I’d recommend The Cat Came Back. If you have kids, they will love it. We could even talk about the theological ramifications of the ending if you want!
Whatever the case, there’s lots to explore on the NFB site.
