Looks like someone watched a Harry Potter movie right before concepting this ad campaign for Mylanta. Just as Harry blew up his aunt until she floated away in the second (I think) Harry Potter movie, Colenso BBDO, who, we’re told, created the campiagn, has people blowing up with gastrointestinal gas and floating away. Mylanta, of course, is there to rescue. See all the ads here.
