Here's one for all you chocolate lovers out there. Long known for its "food porn," Marks & Spencer has been doing some incredible things recently with its food ads. RKCR/Y&R's Adventures in Imagination campaign kicked off last year, introducing a new style of filming various foods being chopped, mashed and twirled to a dance soundtrack (the immensely catchy "Clean Bandit" by Rather Be featuring Jess Glynne.) This Easter offering, which continues the series, is entitled "Adventures in Chocolate," and gives the treatment to eggs, rabbits and more, all in mouthwatering close-ups. You'll crave a chocolate hit just watching. Other ads also promote Easter "sides" to accompany the chocolate, like berries and roasts.
