JWT Spain's European campaign for the upcoming World March for Peace asks viewers to imagine a world where aircraft carriers are cruise ships and fighter planes are taxis. The ship ad is more effective because the voiceover and background music suggest Carnival and Royal Caribbean spots. The fighter plane's kind of a stretch. Most cabbies are pretty surly, and if they drove high-tech aircraft, they'd eject passengers at 5,000 feet to end arguments over the best route to take (as long the fare was paid in advance, of course). John Lennon would've appreciated the sentiment here—not the idea of cabbies ejecting folks from planes per se, but of all the people, living life in peace. Via Ads of the World.
