Saatchi & Saatchi

This spot by Saatchi & Saatchi London for T-Mobile is one the coolest spots I have seen in a long time. I love how during the ad you don't even know what the ad is for, but it is still very captivating. Also, it brings about a sense of unity and puts a smile on your face. I love spots like this where a huge stunt is pulled and it makes you wonder how in the world did Saatchi & Saatchi pull this off so successfully? Props to S&S and T-mobile.
