The Whopper is far bigger than its competitor, the Big Mac. But it’s been a while since we reminded everyone. So to solidify Burger King’s flagship burger as the only proper choice, we came up with a cheeky campaign which left the Big Mac in our shadow, once and for all.

We realised that the Big Mac is so small we could safely put it behind our Whoppers without anyone noticing. So we did. In every single ad we released in 2019. Yup, every piece of print, TV and instore. Then on December 23rd we revealed what we’d done to the world. The secret reveal blew up in over 65 countries and got the world talking, once more, about the size of The Whopper.

While the secret was year-long, the big reveal ran for 7 Days from the 23rd of December. It lived in DOOH in 7 different locations in the UK and in 30”/90” films on Burger King’s social channels.
