This week's compilation of commercials from around the world starts and ends with two very different takes on motherhood made by ad agency W+K in the USA: Old Spice aims for the comedy jugular with a series of clingy moms while P&G's film goes all for an emotional response. In between there's a quirky Ukrainian ad for Pepsi; a claim from animal rights charity Peta that men will last longer if they turn vegan; and a stark road safety film from New Zealand that might just make you think twice about speeding.
