My Favourite Super Bowl ad: Old Milwaukee - Will Ferrell Super Bowl - Dan Kenneally, senior art director, Droga5

The 2015 Super Bowl is just days away, and the advertising carnival already in full force, with major brands gearing up for another multimillion dollar bonanza. We speak to some of America's top creatives for their favourite Super Bowl adverts from over the years.

Old Milwaukee’s Will Ferrell spot was only a regional buy, but it tops my list because it spread like wildfire online after the game. They used Will Ferrell in the dumbest, least efficient way possible, and that’s what made it amazing. No budget, strategy, tagline, story, dialogue or puppies, and it managed to be one of the funniest commercials ever. Dan Kenneally, senior art director of Droga5 offers his choice.
