John West is to launch a TV campaign to support its tuna range. The campaign, titled ‘Shark’, has been created by Leo Burnett and forms part of a &£3m support package for the brand. The campaign breaks on September 16 and the ad follows the theme of John West’s award-winning ad for tinned salmon last year, which showed a bear in kung-fu combat with a fisherman. The new ad shows a struggling shark in a harness, being lifted out of the sea and hosed down by marine biologists. A fish is thrown out of the shark’s mouth and a red hat is visible inside. Presently, a John West fisherman is seen emerging from the animal’s mouth. The ad will use the ‘John West endure the worst to bring you the best’ tagline from the previous campaign.
