BBDO DUBLIN's “Chameleon” campaign for Aviva is so called because it shows one gifted actor transforming himself into lots of different satisfied Aviva customers. The actor is Mario Rosenstock of “Gift Grub” fame, and in this case the character was Rugby Tom – a sheepskin-clad, rugby-mad, loving granddad, who takes all that money he saved with Aviva and lavishes it on his charming grandkids. Pure. Wexford. Beef.
