Perrier's latest TV spot is a colorful, fantastical ode to bubbliness involving hot air balloons gone crazy. Balloons burst out of lakes and forests and rising into the air to the crescendo-ing strains of Grieg's "In the Hall of the Mountain King." In them are a crowd of colorful, partying characters, from a brass band to a gang of cheerleaders and even some wild animals. Things get more and more crazy as the music speeds up. The ad, created by Ogilvy Paris, was directed by French duo Fleur & Manu on location in Argentina, and the fabulous VFX are by MPC Paris.
