No is the story of the only deposing of a dictator by a popular vote - the Chilean referendum that ended the Pinochet regime.
Lovely humorous tone of voice, but didn’t shy from showing the grim oppression of the Pinochet. Also one of the few depictions of marketing people doing something positive - usually they are the villains.
The protagonist is an ad executive who persuades the opposition parties to campaign positively, and create hope. The campaign worked, helping Chileans believe that it would be possible to escape tyranny.
No was filmed on 80s video cameras - it takes a bit of getting used to, but draws you in after not too long.
