Here is the official movie poster for Chasing Mavericks, a new surfing movie releasing tomorrow:
However, below is the one I'm most familiar with, as it appears on the outside of that building I always tell you about, the one on my way to work that has given itself over full time to monolithic movie advertisements:
I don't know how well you can see it, but everything that's dark in this image is an immense wave, the crest of which runs along the upper right third. There's also a miniscule surfer you can see on the far left edge of that crest. In the upper right corner are the words "Actual Size." Yep, that's a pretty effective ad.
But forget these two. Shouldn't this really be the poster for Chasing Mavericks?
