The ad features four comedians from Mischief Theatre saying nice things (we assume) about the as yet unnamed client. 18 Feet is currently running a comedy-based campaign for AkzoNobel, so that may be a clue. Its other clients include Nationwide, which is probably less likely.
Ads used to be live back in the day of course although there was a script. Maybe a trend is developing. Another theatrical troupe Pants On Fire is trying to persuade advertisers to participate in live ‘Ad Breaks’ during its planned performance of a Mad Men-era Pinocchio at this year’s Edinburgh Festival.
