Audi 'the swan' by BBH

Audi UK is promoting its A5 with an advertising campaign harking back to the company's early days as a pioneer of aerodynamic design.

The ad was created by Bartle Bogle Hegarty and directed by the Oscar-winning director Joachim Back.

It is a take on the classic children's tale The Ugly Duckling and features the original Danny Kaye song of the same name.
