The story of that campaign and how García and a small group of fellow advertising executives, the Mad Men of Eighties Chile, risked their lives to stand up against Pinochet and, employing all their advertising nous, inspired a nation to overthrow one of the world’s most repressive regimes, has now been dramatised in a new film, No, which opens in UK cinemas this week and is nominated for an Oscar for best foreign language film. For fans of a certain television series about advertising folk in Sixties New York, it’s a reminder that advertising can, sometimes, be used as a force for good rather than a psychological weapon to make people feel bad about themselves and buy things they don’t need. Its hero, played by Gael García Bernal (a composite of García and his colleague, José Manuel Salcedo), is no Don Draper.
