Overzealous tour guide with a winning smile or bull shark with killer teeth... whose grill are they really checking out?

Developed and written by Discovery writer/producer Daniel Tripod and executed by 2C Creative (“2C”), the spot is equal parts live action and CG, with a clever, humorous approach that has become synonymous with such collaborations.
