This billboard advertising the Day After Tomorrow is guerrilla advertising at its best. The movie billboard is placed in the sea to drown, which is a really awesome idea!
For those who haven't seen the movie, it's a film about global disasters which results in the world being submerged in the sea.
The billboard poster itself is pretty straight forward, but its the location of it that's clever and witty. Its message is totally in line with that of the movie, and you just can’t help but look at it.
