Gael Garcia Bernal is selling happiness in Cannes.
The Mexican actor stars in "No," directed by Chilean director Pablo Larrain, which shows how television helped Chile overthrow Gen. Augusto Pinochet in 1988.
Bernal plays an advertising guy, drawn into the rival referendum TV campaigns _ trying to persuade people to vote "No" to eight more years of Pinochet.
His character uses adverts to sell Chileans the idea of happiness and positive change.
Bernal is also in a good mood.
The Mexican actor and the movie received rapturous applause when it was shown at the film festival's Directors' Fortnight Friday.
Bernal says: "I'm really happy. It's strange, I don't think I've ever felt as confident as I feel now, because I saw the film before coming here and I absolutely loved it."
