“Greenie,” the video response we created for CarMax in less than 24 hours to buy a very used ’96 Honda Accord, won a Bronze Lion at Cannes for Real-time Response in the Social & Influencer category — a new category this year at Cannes.

When we saw the charming spoof of a luxury car commercial a guy made to sell his girlfriend’s used Honda, we thought, who better to buy it than our client, CarMax? And the race was on. In less than a day’s work, we created the video. Shortly thereafter, the car was purchased — and everything in it, too. (Well, not the cat.)
