Lets take a look at what happens if we sub-divide the poster in equal segments.
You know what? Lets take a closer look...
Yep, this most have been intentional...
What is important?
I believe the grid in this poster also helps to accentuate what is important here. You have Steve Zissou/Bill Murray dead center, everyone else in second plane, slightly offset form the line.
Perhaps the second thing you notice is the title of the movie, BIG YELLOW letters also well aligned with the grid. Take a look:
Keep gazing downwards... With who? Steve Zissou? I wonder who that is? Perhaps.... Wait what? There is a fish? Oh!!! They are under water, in a yellow submarine!!!!
I am starting to believe I know what this movie is about.
Two different fonts, both same color. I am actually not quite sure if they are really two different fonts, they both have the same general shape, the curves, sans serif, the perfectly round O, the E who's sections all go all the way. I don't know much about fonts but there might be something here.
All in dark shades of green and yellow, very underwater... Wait, I see some red, you see, their red caps, there most be something about those.
FINALLY, FOR THE FUN OF IT
Apparently, Wes Anderson is famous for his perfectly framed shots, someone actually took the time to make this amazing video.
