Roger Ebert has a list of what he considers the best movie posters of the last decade. And no doubt he has seen alot. This is one of them here (it helps to step back from the poster to see more detail).
Many Hollywood movie posters tend to be predicable, with the art work often taking a back seat to the text. In most of these posters, the art work is predominant.
There are quite a few posters here at Great movie posters of the decade – Roger Ebert’s Journal. It’s worth seeing them all.

Good ref! Now I like Blindness even more.
Yeah, that was a good poster for it. I like that style much better than one that tries to show all the actors in the hope you will go see it just because of that. (Movie posters in DVD rental places are changed to be exactly that way.
