The NFB has put a tonne of their catalogue online at their web site.
As far as I’m concerned, this is one of our national treasures. It’s fantastic that they have decided to share it with everyone.
EDIT: It seems that their link id’s may not be entirely correct. The video I tried to link to was “The Cat Came Back” but it seems to be “Universe”.
EDIT2: I tried using a different link that shows up on the page instead of the one inside the player. We’ll see if this one is correct.
EDIT3: The embedded video is now the correct one and I’ve submitted a bug report to the NFB.
