Speaking of NFB, there was this 80s short film done for the '86 Expo that I watched at a friends place.
It was about 3 world living in one colour (blue, yellow, red) and they all hated each other etc. Then someone in yellow (fascist, I thought it was US) flew over to Red (Soviet Union) fell in love with a girl, but she touched him, and was no longer red. Then the Yellow man flew to Blue (clearly French aristocrat).
Anyway it was great. I can't remember the title. Rainbow Warrior or something.
